Rolling down the West Coast.

WinCo, Beaverton, Oregon (suburb of Portland).

2.7% air is rebreathed. Insane in here. Insane to be in here.

MAYBE 3% in masks. Maybe.

Gobble, gobble. ImageImageImageImage
Cannon Beach, Oregon.

Insane NOT to be here.

495, and no one around. Suspect I have to recalibrate.

Wearing an N95. Because my face is FREEZING! ImageImage
Lots of folks having family, COVID safe Thanksgivings. At the beach. ImageImageImageImage
Shove towels under the door. Crank that window, and wait until the room is perfectly aranetted.

Which means to air out a room until it hits the outside CO2 ppm.

"I can't wait to aranet and crash "
"Do you want to argue about what kind of take-out until the room has aranetted?" Image
I waited until the crowd had left before getting take-out and eating outdoors.

Restaurant was crazy busy inside. And the air crazy free of COVID outside. ImageImage
Cannon Beach, Oregon as I get ready to head south.

Front door open on the marketplace, very few folks inside. Low CO2 ImageImageImage
Cannon Beach Gallery. Door open. Excellent C02. ImageImageImage
Rockaway Beach, Oregon.

Grumpy's Cafe & Bakery must have very bad ventilation, I assume, from the general grumpiness and skeletons.

And turkey in a bathtub, next to the skeleton dancing on a telephone pole like it's a stripper pole.

Strange things afoot.... ImageImage
Strange things afoot in Rockaway Beach, Oregon.

The towns people are a particularly surly lot.

Hustling to move out of this swirling CO2 Bermuda Triangle, a falcon with a fish, crosses over the road, affixing a baleful eye on me.

Go in peace, Falcon Man, go in peace. Image
They wait, hidden in the beauty.

For the unsuspecting. Image
Meg's Beachwood Bar & Cafe,
6425 Pacific Ave, Cloverdale, OR 97112

1000 ppm CO2 with just 2 bartenders, a lounge singer (playing piano in vid), and me in the 3MCool Flow Respirator.

Freezing, so sat next to the infrared quartz fake fireplace.

If it was propane? Easily could twitter.com/i/web/status/1…
have been the source of the CO2.

Both employees were flushed and tense when I went in, so suspect a yelling match.

Bonus:
One had the ole Covid cough.

COVID in a bar? Also called the Devil's Punch Bowl.

Which I also stopped by.

Now? Sprung for a motel with no shared HVAC. twitter.com/i/web/status/1… Image
Has own door, and I am running the bathroom nonstop to make sure that even if it shares a stack?

No backflow will happen. I used the old tissue check to confirm.

Some shots from along the way, below.

(Food from Meg's was amazing and I took it to go. The tots were dandy.) ImageImage
Newport Bay, Oregon. Stopped off at the Pirates Plunder, after seeing a beautiful marina and waterfront.

Antique malls typically have pretty bad ventilation. ImageImageImage
It got up to 1040...which is not bad for these places.

But my bigger concern would be the cramped aisles with the little cubbies. Those cubbies, like plexiglass, would act as little dead zones of concentrated aerosols.

Fun store - if you are in an N95 or better. ImageImageImageImage
Yaquina Lighthouse Interpretive Center, Newport, Oregon. Bathroom up to 900.

The rest? Someone has been upgrading the HVAC. Damn good, @BLMOregon. Wow.

They also had HEPAs everywhere They don't clean CO2, so those 500 readings are just amazing.

Wow. Just impressed. ImageImageImageImage
Tight trails, I thought, to see Quarry Cove, so had N95 on. Some yutz gave me the stink eye.

Gave it right back because I'm a member of the big ole boy club.

Jump in the car and random Longhauler conversation on NPR.

Affirmations and confirmations are out there. Clean air. twitter.com/i/web/status/1…
Sea Lions Cave Gift Shop, Florence, OR.

1241 CO2.

No one with masks on - a lot of Indians in here (I've off-shored off enough departments to India to recognize the language at least.).

Plexiglass surrounding the cashier's station.

Below is the Heceta Lighthouse. ImageImageImageImage
The sun set on the nice weather.

Camping out deep in the woods, using the app iOverlander amongst others to spot free camping if possible. ImageImageImageImage
Woke up to rain, which should see me out of Oregon. Very grateful for the two beautiful days I had.

Getting breakfast at Dishner's Fine Dining in North Bend.

Hit above 1000 ppm while waiting for my take-out Avocado, Bacon, and Cheese omelet.

The "Leaven No Trace" sign-funny. ImageImageImageImage
This Chinese CDC study on rock solid evidence of outdoor transmission is now effectively changing my behavior to be even more protective of my lungs.

Picture from yesterday. A tree's shape reminds me of lungs.

No time to search for a study to confirm, but I'm sure the shape of both is similar for functional reasons...thus evolutionarily optimal. Image
Empire Donuts & Dawgs. Coos Bay, Oregon...523 ppm CO2.

Had to stop because where else can you get a doughnut AND a hot dog?

Is this where their empire starts?

Doughnuts were pretty doggone good, I have to say. ImageImage
#NovidROADtrip-. Passing on CO2 measurements and airborne disease transmission prevention tips on a very practical level.

Walking the walk.

Reached Brookings, Oregon. Blue Coast Inn, just north of CA border.

Check in to motel room with no shared air? ✅

Preferably single ImageImageImageImage
story so no shared ventilation stack (bathroom fecal aerosol transmission)? ✅

While wearing N95, checked in and opened room up to vent out until CO2 matches outdoor CO2 and another 15 minutes to be sure? (I turn bathroom fan on to expedite the process.) ✅ 👇 ImageImageImageImage
Motel room has its own door? ✅

Ruminate on the fact that the ARANET4 CO2 monitor also reminds of us of how much CO20 is already in the atmosphere? ✅

Ponder how big insects and aliens will get again in the future as the Earth warms? (No, but a fun thought.) ImageImageImageImage
The #NovidROADtrip tour continues. Last interpretive center in Oregon before CA. Oregon's ventilation in these centers is top notch. In the 500s.... ImageImageImageImage
The #NovidROADtrip tour continues.

Checking out the Stout Grove, in the Jedidiah Smith Redwood State Park.

Trails get pretty narrow so wore my N95.

Taking lots of pictures, but scale is hard to show with these huge trees.

Turns out the N95 makes a fine scale tool. ImageImageImageImage
In this first pic below? Look up.

I have to confess that I was cracking myself up climbing all over these huge trees, and putting the N95. Donning protocol:

✅ Yellow straps could not be visible.
✅ Had to look at plausible as possible. (Hee hee ...so silly of me). ImageImageImageImage
The #NovidROADtrip tour continues.

Got soaked yesterday, so needed to hole up and do laundry. Cheap motels are booked as everyone else is in the same predicament.

So, this hotel - which is actually a motel with every room having it's own door. No corridor shared air! ImageImageImageImage
Complementary breakfast with excellent CO2. But I just do not like inhaling shared air while inhaling my complementary Chex, OJ (like drinking Caviar at its prices), biscuits and gravy. ImageImage
The #NovidROADtrip tour continues.

Hitting the Drury Chaney Groves trail. Trails are narrow.

Wind? None. 46 degree F.

Yep, wearing the ole @3M 8311, available at every @Lowes.

Walk past a few folks, felt their air.

Too cautious? I can't evade their aerosols as well ImageImage
as the latest variants can evade the vaccines (decreased efficiency), or evade ALL MAbs including bebtelovimab.

Every day delayed is a day closer to a cure for LongCoVid.

You get LongCoVid? It doesn't come with a Fast Car from Tracy Chapman.

It comes with.

Loneliness. Pain. Image
It comes with loneliness, because those with chronic diseases? Have a long history of being left.
At the Redwood Gifts Redcrest Resort, a 708 ppm CO2 does not seem bad. Till you realize that was just the owner and myself in there...and whomever was in there before I walked in. ImageImage
#NovidROADtrip- had a pleasant chat with a fellow traveller from Washington. Let's call her, Clara.

Clara, like most of America, is stuck climbing the Sisyphean hill that is the @CDCgov Confusion Hill

She is eating in restaurants, and thinks COVID is over.

She mourns the Image
loss of her COVID careful friends, and even the fact that most places in small town America continue to have shortened hours.

She can't go get a cocktail after work, anymore.

Of course, the real story? Her COVID careful friends know it's ongoing.

More Americans than not,
know it's ongoing. Thus the shortened hours? Caused by a lack of customers (staying at home), and employees (LongCoVid).

Know what businesses hate more than anything? Confusion.

Biden will be reaping what he has sown. And making cake from it.

One more thing Clara shared.

She lost her 63 year old best friend best friend on August 20th. He was hanging with her at her house and all of a sudden pitched to the right and over her deck's fence.

He landed on his neck, 12 feet down. Despite them doing CPR, he never Image
regained consciousness.

I gently asked if they thought he had a heart attack or cardiac event, and she softly said yes.

She is not COVID careful, so chances are this was a COVID event.

Fortunately, the @CDCgov is looking into this and will let us know if we should go out Image
of our way to avoid Covid.

These things take time since 2 years have come and gone since the CDC started looking into this.

They'll let us know, right?

They'll let Clara know, right? Image
#NovidROADTrip. Got a burger at a small casino near Point Arena Stornetta Nat. Monument (also camped in their parking lot, using iOverlander to find free spots).

Amazingly low CO2....but I never eat inside, so ate in the car. twitter.com/i/web/status/1… Image
This morning, down at the Pt. Arena Pier for breakfast. My first Avocado Toast! Anyone who makes fun of that should be mocked for at least 15 minutes.

As should those who mock us for being COVID Conservatives.

For in reality, do we not actually walk that damn walk? Image
We don't want to waste our money on hospitals.

We don't want to waste our lives being sick, when we could be spending them enjoying the outdoors. The hunter - the conservative.

The pic above - the fisherman? Conservative.

The farmer? Conservative. ImageImageImage
So, although the cafe was deserted with excellent CO2?

I still didn't know if the barista would suddenly cough (18 feet), sneeze (27 feet) - both which can be autonomic and out of our control.

Like a good COVID Conservative. And good things come - like a very happy random dog! ImageImageImageImage
#NovidRoadTrip. This will be controversial, but so be it.

I am in Bodega Bay,where Alfred Hitchcock shot part of "The Birds."

Obviously, only non-flying birds like emu's need be feared (disembowel you with one kick).

But other flying/floating things like aerosols ImageImage
can cause you horrendous GI issues.

Such as with COVID.

I always carry an N95 with me.

And yanked it on before I walked up to the people on the trail below. They gave me a look, but I'd rather get a look, than have them give me Covid. ImageImageImageImage
Point Reyes! Home of the Bovine Bakery and Palace Market with excellent CO2, and every single employee in KN95s - and a surprising KF94.

Also, a killer public phone booth, and a thrift shop with an awareness of ventilation?

No wonder Monica Gandhi is so comfortable advocating ImageImageImageImage
for demasking.

Marin County, like Newton, MA, has busted out the ventilation awareness.

Impressive...much like the National Monument, itself. As impressively beautiful as the fog in Sonoma County. ImageImageImage
The Point Reyes Visitor Center has low CO2, impressive air volume, and a HEPA, Medify Air MA-112.

Not a recommendation, but here it is:
medifyair.com/products/ma-112

As always, cleanairstars.com to make your air cleaning recommendations. ImageImageImageImage
At Sausalito, across the water from San Francisco, at Target, doing an informal survey.

2 out of 35 had any kind of face covering on.

Evidently, Covid stops at the Golden Gate Bridge.

(Just a little bit of snark, because just up the road at Point Reyes? Employees in respies.) Image
Every big city seems to have a Mission Street. Cruised up there and parked and just listened.

The coughs were impressively deep - and loud.

The well-to-do get infected less, but when they do, cough in the comfort of the home.

Same as it ever was....

#NovidRoadTrip - what makes this possible besides an ARANET4, N95S, N100s?

A 2007 Honda CRV with one rear seat removed and a small sleeping platform built-in. Top cargo carrier for things rarely accessed. Rear cargo carrier for cooking gear.

Reflectix blinds cut 4 windows. ImageImageImage
7 gallon water container for water.
Pop-up privacy shelter and pop-up toilet.
Cooking gear and a 7 day cooler.

Only stay at motels with outward-facing doors.

Because I am using the app iOverlander to find free camping spots? Gas and food are my primary costs.

If it is ImageImageImage
raining? Take-out!

Finally, the knowledge that #COVIDisAirborne - and the simple knowledge that comes from needed to travel safely.

(The picture below was fascinating to me to see such a deep crevasse lined with pampas grass.) Image
#NovidRoadTrip....Davenport Bluff yields an amazing tableau after walking along a skeeeeetchy "I'm gonna die, worth it cause beautiful" cliff path.

Across the street the bakery has amazingly low CO2. twitter.com/i/web/status/1… Image
After determining how many blue berry muffins and Chihuahuas are there?

484 on the ole CO2 Richter scale.

Why? Two front doors open, and the rear door open with the constant ocean breeze pushing air through the restaurant.

The ONLY employee with no mask on? The chef.... ImageImageImageImage
Which is ironic given that BY DESIGN, restaurants have air flowing from the front of the house to the back.

And cooks have some of the most Covid dangerous jobs.

And it does not have to be this way.

Hong Kong mandated 6 ACH for all restaurants.

King County in Washington had their Air Investigators hand out free HEPAs.

#NovidRoadTrip - While waiting to see if @Costco will make their pro-infection policy a little less @friendlycovid19, and a little more friendly to those of who are #immunocompromised or have #LongCovid.

I don't, but if you have it, getting Covid will

lay you out flat - again.

And hey...that's only 30% of the 100 million Americans, @Costco - but who's counting?

Anyway, tonight I'm in Santa Cruz.

Not really wanting to cook, so in my handy N95,I find Charlie Hong Kong.

With an order and pickup window. Outside ImageImageImage
(side-eye @Costco.....).lp

Before I got to Charlie's though?

$20 for a shower pass @24hourfitness.

I was there about 6:30 pm, so was expecting worse CO2 at 1017 ppm - when I first walked in, while holding my breath.

So, that 1.5% of the air being sucked in that humid locker ImageImageImage
room? Was air straight from others lungs.

Not mine.

N95? You damn well know it!

My lungs are a CoVid-free zone. And boom shock-a-locka comes the @readimask. The only N95 that I would trust with haircuts or showers.

It keeps my lungs as beautiful as the murals here! ImageImageImageImage
#NovidRoadTrip

@k_macC_ - thank you for the Gayle's Bakery recommendation in Santa Cruz!

The Ham & Cheese Croissant was amazing.

As was the lack of masking. Wow!

While the CO2 was low at 743, that will not matter with the near field aerosols.

There were so many people ImageImageImage
coming and going, there was no way I'd eat even on the cute benches outside.

The C02 in the attached tent structure? Worse than the building itself.

Now, that could be if that fire was propane..... ImageImage
At @Vervecoffee getting a cup of coffee before scooting down to Monterey to pick up an Amazon shipment.

Oof. 1272 ppm CO2 (2.2% of each breath just in your neighbors' Covid lungs) thanks to 50 people yolo'ing. (@k_macC_).

A shame. Two huge opposing doors could be open. ImageImageImageImage
#NovidRoadTrip

After a quick take-out "Bacado" omelet from Monterey's First Awakenings, where the CO2 hit 831 ppm, eaten down at the waterfront. twitter.com/i/web/status/1… Image
It was time for the Monterey Bay Aquarium.

This one I was in the GVS, P100. Because people get UP CLOSE in aquariums.

Did you know that turtles have ACE2? They were thought to maybe be an intermediate host.

pubs.acs.org/doi/full/10.10… Image
In November 2021, the Aquarium gave the sea otters vaccines.

thedailybeast.com/monterey-bay-a…

But the variants are now immunoevasive. When I watched the feeding, I did not see N95s - ahem @MontereyAq.

If you look at the CO2 inside at 710 ppm? Not bad, but not consistent. Image
A crowd of people had just been in this area...it went up to 2570, but I snapped the shot at 2013. Image
But the CO2 was all over the place.

As were the unmasked. And the sound of tiny coughs from some of the children, most of the toddlers and every single baby.

Hacking guys pushing in next to me, behind me, in front of me. ImageImageImage
Completely worth the $49.95.

Today.

But like their "Real-Cost Cafe" points out. That bluefish tuna is tasty today, but at what cost?

In the cafe, a CO2 ppm of 921, placed ironically by me above the hand sanitizer.

No sign asking people to mask up. Image
At what cost are we just letting Covid rip?

At what cost is the aquarium not requiring masks?

What are a few sea otters or sea turtles?

Just like people, we have more, right?

Right?
Best coffee in Monterey, CA is Captain Stoker per the Googs. Kudos to the partially opened garage door and front door to get that lovely sea air diluting.

636 CO2 ppm, but man, it was packed. ImageImageImageImage
Ugh. Turns out the owner is one of Panantir's Thiel's right-hand men.

My coffee just curdled.

montereycountyweekly.com/news/cover/for… ImageImage
#NovidRoadTrip

Big Sur Lodge - little store attached next to it had amazing ventilation 506 ppm CO2.

And a very interested, yet confused, cashier.

"That measures the same CO2 as with climate change?"

"Wait, why hasn't the CDC told us about reinfections are worse?"

"It's ImageImageImageImage

A new study just showed what I have been saying since the start of bird flu. H5N1 is airborne.

Still in place?
USDA: YOU ONLY NEED TO TEST LACTATING COWS.

oops.

USDA: FOMITES (infectious objects) SPREAD IT.

oops.

WASHING YOUR HANDS WILL STOP IT.

oops. This new Federal Order does not override or supersede USDA's April 24 Federal Order, which still requires the mandatory testing of lactating dairy cows prior to interstate shipment and requires that all privately owned laboratories and state veterinarians report positive test results connected with those tests. The new Federal Order announced today is intended to complement and enhance this existing order.
Question [00:51:52]  Given the CDC's vaccination program, I'm wondering if this means you think it's no longer realistic to expect that the outbreak will be contained this year?  Eric Deeble, USDA [00:52:12]  Just on the animal side and all that Dr. Nirav speak to the human side, there's a lot about this disease that makes us feel as if we can arrest its progress.  And we've actually seen some success demonstrated to date.  With this disease, it does not appear to move by respiratory transmission. We know that there are high viral loads in milk, and we've identified through close, collabora...
In addition to testing, biosecurity is the key to containing this virus, and ultimately ensuring that it is eradicated so that producers do not have to deal with this virus in dairy cattle permanently. Good biosecurity including cleaning and disinfection of vehicle and equipment - is critical to minimizing the risk of disease spread. USDA works closely with state animal health official, producers, and industry organizations to provide guidance and resources for cleaning and disinfection not only on affected farms but for all livestock producers as a part of practicing good biosecurity. APHI...
The study.

✅ 20% of the cows showed up as sick. Had symptoms. But....

✅ It turns out that 89.4% were actually infected.

✅ 83.7% of those had no symptoms. Remind you of any other airborne diseases?

✅ 40.5% of the dry cows not being milked? Infected. So, no Image

fomites or milk aerosols involved, most likely.

There is not much that scares me. Freaks me out.

I am freaking out.

You should be, too.

Do you know what this shows?

Do you know how to avoid this? Holy cow.
This is the continued accumulation of dementia-causing microplastics in your brain. Simple linear regression (shown with 95% CI represented by dashed lines) was performed for total plastics, polyethylene, polypropylene, polyvinyl chloride and styrene-butadiene rubber measured in normal decedent brains from 2004 (average of east coast samples), 2016 and 2024 (NM OMI samples).
See how it increased from 2016 to 2024?

And it actually is worse - they found less plastics in brains from a decade earlier.

Great interview of Ed Yong - I am just covering the C0V1D part.

/1 The Interview  Ed Yong Wants to Show You the Hidden Reality of the World  Ed standing with his arms folded.  His eyes tell you COVID is not over.
You've been clear in saying that C0V1D has not gone away. You ask people to wear masks at your events..... You’ve been clear in saying that Covid has not gone away. You ask people to wear masks at your events. But that attitude is not necessarily where the rest of the world is. How do you think about continuing to take precautions and advising others to do so when it feels as if society has moved on? I do it for a bunch of reasons. Firstly, I have learned that I enjoy not being sick. I know that the cost of long Covid is real and substantial, and I don’t want to run that risk lightly.
"I think it makes a huge difference to them to have the person at the front of the stage wear a mask. It tells them, It’s not weird." . I also know that I have many friends and people I’m close to who are immunocompromised. So for the sake of the people around me, I also don’t want to get sick. When I do events, I wear a mask for those reasons, and because I know that every time I do a talk, while the vast majority of people in the audience have probably moved on, there are going to be other people who haven’t. I think it makes a huge difference to them to have the person at the front of the stage wear a mask. It tells them, It’s not weird. So I do it for that reason, too. In terms of holding this line at a point when a l...

I am sorry if this will upset you. A lot of people depend on NASAL SPRAYS for C0V1D.

I have been iffy on them, but viewed them as "if they don't hurt, why not" but not for me.

There's an analysis
on Reddit that you should read in detail, and make up your own mind.
/1
Here is the link:


Here is a 4 tweet TLDR version.

Here is how it starts - the author goes HARD at the underlying studies. reddit.com/r/ZeroCovidCom…There is no convincing evidence that nasal sprays prevent COVID-19  There is a lot of misinformation out there about nasal sprays preventing COVID-19. Unfortunately, there are no convincing studies showing that nasal sprays prevent COVID-19. The published studies investigating whether or not nasal sprays prevent COVID-19 each have major issues, which I will detail here.  I have a PhD in biochemistry and one of my PhD projects was on COVID-19. The main takeaway of this post is that there is no sound evidence that nasal sprays prevent COVID-19. Thus, nasal sprays should not be used for COVID-...
Some pretty harsh language, but to me the important thing is we still have clean air.

Which is good, because it boils down to only 2 studies saying that nasal sprays work, per them. 5. Summary/TLDR and final thoughts  Unfortunately, many people including covid influencers have fallen for the grift of nasal sprays preventing COVID-19. Some such influencers have promoted these nasal sprays for free and helped spread the misinformation that they prevent COVID-19. Unlike with nasal sprays, there is ample, sound evidence that high-quality well-fitting respirators, ventilation and air purification prevent COVID-19.  The human clinical trials testing whether or not nasal sprays prevent COVID-19 are garbage, and to my knowledge there are only two! Please don't lower your covid...

Guillain-Barre Syndrome linked to poultry eggs? H5N1?!

The BBC had a good article from February 3 that talks about how these Indian states' cases are linked to campylobacter jejuni, a bacteria. It IS the most common root-cause, globally.

And IT is commonly found in poultry. AVOID CHICKEN AND EGGS RIGHT NOW SIGN showing for the country of India in a tweet from @alwaysmadesh.  Due to Guillain-Barre Syndrome.
"Campylobacter jejuni infection is the common associated microorganism (25–40%), followed by cytomegalovirus (6–15%), Mycoplasma pneumoniae (3–21%), and Haemophilus influenzae (1–9%)"

BTW - Cytomegalovirus is also an airborne virus - that just happens to cause brain cancer.
Mycoplasma pneumoniae - also airborne.

And...drum roll please...Campylobacter jejuni also airborne.

Don't get me wrong - jejuni most definitely is also fecal-oral, no question.

But it's also airborne.

Sampled from the air below. Figure 7. GCN/m3 results using microorganism-specific primers. These microorganisms were chosen for their pathogenic and opportunistic nature. Samples 1–12 indicate the WWC collections in House A, 1R–12R the WWC collections in House B and 1F–12F the filter collections in House A.

Just a little bit closer to acknowledging H5N1 is airborne.

3 vets asymptomatic, + for bird flu antibodies. Did not wear respiratory gear or glasses.

Did wear gloves and coveralls - so rules out fomites.

One practicing in states with NO H5N1.

Vets get very close to /1 No seropositive practitioner knew that they were working with dairy cattle with known or suspected HPAI A(H5) infection. None of the seropositive practitioners reported wearing respiratory or eye protection while providing veterinary care to cattle. Neither respiratory or eye protection is recommended when working with uninfected animals in regions without confirmed cases; however, safety goggles and a respirator are recommended when working with uninfected animals in regions where there are confirmed or potentially infected animals (4).
Among 150 bovine veterinary practitioners, three had evidence of recent infection with HPAI A(H5) virus, including one who only practiced in two states (Georgia and South Carolina) with no known HPAI A(H5) virus infection in cattle and no reported human cases (1,2); this practitioner reported no exposures to animals with known or suspected HPAI A(H5) virus infections. These findings suggest that there might be HPAI A(H5) virus–infected dairy cattle in states where infection in dairy cattle has not yet been identified, highlighting the importance of rapid identification of infected dairy cat...
