Hunting in the snow is way overrated. Yes, it's good for tracking but you're tracking because the animal heard you and took off. Snow is usually squeeky or crunchy. Frozen snow is way too noisy. Of course, you usually don't have a choice. If it snows, it snows, and you aren't going to change it other than by staying in camp or going home.
That said, I've taken my share of deer and elk in snow.
