Yes, all this is good info., but I tell you, whether you believe me or not, I have stalked up to or had deer come to me without the favor of the wind, and I mean up to a few yards away, no explanation other than the soap and carbon clothes, but also doing my part as far as keeping everything clean. In studies they have found that most of your scent comes out from your head, hands, and mouth, and as long as you are doing your part to to keep everything clean it seems to work pretty good in N.J.
You must remember, here we might hunt on a big parcel of land and have plenty of area to stalk and then again it might be a postage stamp like what I have now since losing 1500 acres to new development. The area I hunt on now is about 2 acres and most of it is grass. The area I hunt on is about 25 yds. wide dwindling to about 10 yds. of woods and about 60 yds. long. So no stalking, or playing the wind. I did have a huge buck about 12-15 yds. from my tree but no shot, wind was blustery to say the least, but he never busted me and it was going straight to him and the direction where he came in from. He finally just walked away from where he came from.
