Been peeing off my stand for years, with absolutely no effect on deer. As stated in previous post, deer do not associate human urine with people or danger. As far as using a bottle, some years ago during gun season, a older friend of mine used his sons ground stand, which his son used the day before. The son urinated in a 20oz. diet MT Dew plastic bottle, and left it in the stand. Yea, you can see where this story is going. True Story!
