I wish I had some photos of the fog we'd get in southern Germany or in eastern Bosnia-Herzegovina. Visibilities were less than 20 feet--no joke. I remember nights trying toward base. The fog was so thick that it absorbed all the light. A bright, glowing base appears as if it had vanished. Stop lights are meaningless. By the time you see what color the light is, you're already in the intersection. Street signs are not visible. Navigation is done by memory--no visual clues to help you out.
Those were interesting times.
Anyway, great photos, Sandy!
