I really don't think you ruined your top location at all. if you are worried about that happening next time dig a little hole go there then bury it with some cedar chips or something. but I don't think deer link crap and humans together but then I am not a whitetail expert. I usually don't have to go when I sit all day. I go before I leave and when I get done hunting. make sure you don't eat anything the day before that will effect you in a bad way the day you sit, also I know for me coffee is bad I never drink coffee the morning I am hunting or that day at all, and don't bring food to your stand that will go right through you. But if you have to go you have to go and like I mentioned just bury it with cedar chips or something like that. Good Luck.
