Well, that was interesting. I was just out walking an errand. I've been in fog, entered fog, watched fog move, been out on the Venice Pier in Los Angeles countless times at midnight, fishing, and watched fog roll in. But I've never had fog form around me. I thought maybe my eyes were acting up or something.
No wind, temp is 47F, dewpoint 46F, so a slight variation in temperature or barometric pressure is all it takes.
@karlauerbach Yes, including Covid fog, my case. But this was visual. Hah.
