jred,
Not to sound mean or anything but this very topic has been beaten into the ground about 100 times on this forum.
Not sure if a search will still turn up similar posts but give it a try.
In any event, to answer your question...absolutely not!! Many people even dress up scrapes with human urine. I've relieved myself right off my stand and had a deer 1/2 hour later checking out the spot. The deer never seemed alarmed.
The only real problem you face would be that the urine smell could keep the deer under your stand longer. That would increase the chance that the deer will catch a wiff of you should the wind change.
Think about it for a second...If deer were alarmed by the smell of predator urine, wouldn't they be
constantly running away from all the coyote spots, wolf spots, bear spots, etc?
