But in recent years there's a ton of evidence that human urine doesn't bother deer a bit. In fact, I've been peeing in my mock scrapes the last several seasons, and for the most part it drives buck crazy...in a good way. So acting upon the evidence I'd heard from other hunters who "let if fly" off the stand, and my own mock scrape experiments, I decided a few years back that I would no longer tolerate the muss, fuss and mess of a pee bottle. I've found the experience liberating, and to the best of my knowledge, have not spooked a deer with my scent-marking.
