The farm I hunt has two stands, one at the north end and one at the south end. Two of us hunt it. I killed 3 deer there last year. We can't hunt the wind, my buddy smokes on the way to the woods in the truck and smokes while he hunts. I used to smoke and have killed deer with a cigarette in my hands.
I keep my bibs in a large plastic storage bag and sometimes use a sent wafer but that is it. I see more then my fair share of deer coming from all directions.
I had a guy tell me once that deer will ALWAYS come in from downwind, every time. I told him if that was the case they would all be standing on the beaches of the east coast, they can't all be downwind of everyone.
