these guys are right on about smell being the thing. And if you are using one particular stand--I would spray the hell out of it and yourself (especially exposed hair and skin) and still hope for the right wind. Movement and human noises being second most important--Use slow--SLOW--deliberate moves. and avoid any metallic sounds (ex. tree stand creaking) and coughing if possible (I use the cough silencer--no I don't). Be absolutley sure of your target before you aim that thing, make sure your strapped into that tree. Be careful w/that thing in the tree--lot more self inflicted broadhead wounds then gun wounds. You'll be fine.
