I grew up in a area fog was a very common weather condition, some days couldn';t see 25 ft
hunting in it sucked, needed to really know your way a or could get turned around real easy
it was the only place I ever seen crows and Turkey buzzards WALKING thru the woods, as I guess would be too foggy for them to fly??
But I always did see a lot of deer , they moved as if normal, could be due to they had that weather as often as they did and got used to it
but it seemed like they were fine with moving in it, as they too could sneak about in it, they would like magically just appear in your shooting lanes and then 2-3 steps be gone?
kept you on your toe's
a side note, it still amazes me HOW few folks that drive in the fog, turn there darn headlights on
these moron's around here just drive like its a clear day time day??
headlights don't make HUGE difference, but when visibility is 50-75 ft, any help is a huge PLUS!!
