RE: Going to the bathroom...
I say let her fly. Humans don't produce pheromones. I believe deer cannot pick up human odor on human urine. They may know it was a meat eater that produced the urine, but it stops there. I feel it does not spook deer. I have done some non-scientific testing by relieving myself in a known spot out in a field in front of my stand before the hunt. I watched for deer reaction. There was no reaction.
Granted if you can keep from doing it you're better off, but I don't hold it and don't bottle it anymore.
