No need to pee in a bottle, either... many studies have shown that urine has no discernible smell distinguishing it as "human" or "predator" and it doesn't bother deer.

There's always those who say they don't know, but I've peed from too many stands to think otherwise. In fact, this guy was taken on Dec. 26th... after a HARD year of pursuing him. I finally got an arrow through him on the SIXTH time I saw him from stand -- and I pee from all my stands when I have to. He never had a clue I was hunting, as he walked right under me once (no shot opportunity) and was behind some brush at 30 on another instance; neither time did he spook then, or at any time.
