RE: potty break?
I go right out of the stand. I've evenshot does and a few small bucks after urinating earlier.
I even take things a step further. I urinate around my tree stands several weeks before the season starts. I've taken deer from those stands also.
I figure the deer wiil get use to my smell the same way they would get use to a ground blind. After a while they don't pay attention to it.
I even shot a spike while squatting over a pile of crap one time. Shot it with my pants down and all.
I was still hunting during the archry season, when I couldn't hold it any longer. As I was squatting ther, relieving myself, I looked up and saw a spike about 70yds. away watching me. It must have been curious and had to investigate. At 30yds, it went behind a large oak and I drew my bow. It came out the other side and stood there. I double lunged it as I knelt over my pile.
