CO2 workout

So that Vitalight monitor got real use today, as I went and endangered myself.

Met a friend at a taqueria, eating outside. Not a ton of risk there apart from having a traveler talk at me. I was checking out of curiosity, registered 750 ppm at one point but that's probably from being between 2 people talking. But then I went to use the bathroom and that was also in the 700s.

Then I went to an alumni meetup, in a bar, though very well ventilated; CO2 around 600, nice. I still stepped out to drink some water, CO2 means less when people are talking at you.

Afterwards I passed a donburi place with lots of room, no customers, and an open door, and got tempted to eat there, by the door. CO2 around 550-600.

Finally the bus home, which scored as high as 1100, before most people got off and it started slowly coming down again. I guess the ventilation is slightly more powerful than 3 seated people exhaling. Gee, must be really fun when really crowded. One of the newer buses so you can't open the upper windows.
