Hunting in the snow is the best. The Deer show up visually at very long distances. You can watch them forever. As far as heavy snow I would go for it. In past years I have taken Deer in all kinds of nasty weather. Tracking in the snow is the one of the things I really enjoy. They can't get away.Last weekend it was 8 degrees when I went out with 4 fresh inches of snow, I saw 23 Deer and took a nice Doe.
