Wear good boots, warm socks and watch your footing so you don't slip. Snow is nothing to concern yourself with. Hunting wise, it works to your advantatge. You can see them coming much sooner as their movements stand out much more, it is normally more quiet to walk in then dried leaves, foot prints are easier to follow then marks in the dirt, blood trails and hits are easier to spot. When there is snow on the ground I consider myself a lucky hunter.
