RE: Hunt when it's snowing or after it snows?
If I have the time, I like to hunt during the snow b/c it's just awsome...then after the snow, especially if the snow stops just before sunrise, I like to get out there and use it as some later-season scouting. I've seen it where there's 1.5-2'' of snow on the ground and does still beat their trails to the point where it's almost solid dirt. Set up on the less traveled parellel trails and that's my paydirt.
