I always bowhunted from the ground. I usually am on a super steep hill or cut my way into a sticker patch to shoot outward. I have had deer 10 feet away right after I put out a cigarette. Even a breeze so slight it barely moves a downy feather is enough to cover you. If the wind does swirl a little the deer usually don't take off because they don't know which way to run. The older ones start to look in the trees behind me. I think that climbing into a tree is really a way to disperse scent. If I use lure, I throw the rag up in a tree as far as I can and that gets good results. Get the picture?
