Some of us talked about this in another thread......it involved a bear too, but that's another story....
Urination, I just let it go wherever I'm standing at the time. Deer pee smells worse than mine does.
There's no way you can tell me that my crap smells any worse or affects deer anymore than a mangy dog coyote's crap or a coon or possum or any other animal that's been eating whatever nasty stuff they find. When I need to go, I go. My biggest worry is stepping in it later...

I go away from any place that I might walk later, meaning trails and such. Don't forget the TP, it stinks (pun fully intended) to ruin a nice camo shirt when you don't have anything else.
Yep, been there, done that. My punk cousin that hunts with me thought it was so funny that he got some of those mini rolls of camper TP for christmas one year. One day he forgot his TP. I thought that it was really funny. I did NOT lend him mine. That was even funnier.
If you're worried about the smell, most everyone carries/uses some kind of scent killer spray nowadays. I'd think that soaking the "spot" with it would take care of the smell.
