Believe it or not, I have never had to take a dump while deer hunting. That's the first thing I do when I wake up in the morning! I'll take a leakfrom my stand when ever I have the needto though.I am convinced it doesn't phase a deer (my opinion) at all. I used to use an empty Gatorade bottle as well, and I learned how noisey they can be when they're empty. So Iwould wrap it with hockey tape to make it quiet. That worked very well.
