I've always said cover scent is a crock of bull. However, I do like to keep clean if I can and keep the foreign odors down. I always play the wind but it seems to swirl and shift in the hills and hollows where I hunt. This makes it tough to hunt. Also just getting to my hunting spot is tough without leaving scent for deer to spook. The best I can do is not over hunt it and use the wind the best I can. The deers nose is something special and not to be taken lightly.
