@saab,
I miss fog - there was fog in my area by the coast in Los Angeles, and often fog in the San Francisco area (where I never lived but often visited friends) and fog a lot of the time when I drove through the redwood forest north to the upper north California coast - none of that scared me. But, there's a famous fog in central california, tule fog, I think they call it, which can shut down highways and wreak massive car crashes.
I do remember driving north in the SF area (280, right near the water) once in heavy traffic slowly, cars very close to each other - that wasn't all that scary as the drivers knew what they were doing. The highway in central California is a speed festival and I gather the fog is "denser", but I've not driven in it there.
A couple of my paintings involve fog..
