i have yet to have a deer wind we this year except for this last weekend. I believe it was because of the fact that i took a "grow em right" book with me to the stand and it had been exposed to a great deal of human odor previously. I also had a dip in so that probably didnt help much either but i didnt think the deer would be moving much at that time woops! the good thing was that it didnt fully spook him he just walk behind me( down wind of me) and stopped suddenly and jumped a little then walked off in the other direction. No big deal because a very nice 8 point came in right behind him( right after he beat the crud out of another smaller buck that i got to see AWESOME sight i might add)
