If it were the size of mine, it would reach the ground!

FWIW, I did a bit of research many years ago. I'd always carried a pee bottle with me, but at one point, I decided it was not worth the effort. One morning I pee'd out of my stand and it had zero effect on how the deer acted, except for the fact one little button buck and his little sister walked right by my tree and stopped to sniff the wet spot. It didn't seem to affect their behavior in any way. I killed a nice 7-point (plus a couple of stickers) that day and from that point forward, I just started peeing out of my stand.
