well i guess it would also depent for me too what kind of hunting i was doing. if i was gun hunting and looking at shooting a deer at 100 yards away i wouldnt care, heck i would even use the scent control products to mask myself, deer come that close to the house. i guess im speaking more in a bow hunting mind and thinking of geting the deer in under 20 yards. we as humans may not look at pee as animals do but they use it for every thing, breeding, teriroty, fox use their unine to keep track of the areas they search at night for food as kind of perimiter markers, and to me putting freash warm pee on the tree would tell any animal that some other animal (sure mabey not a human but if you smelled urine all the time like they do,.. who knows ) is in the area and they go around and avoid it at least the big buck will i bet, of corse the little yearlings will run right in and check it out caz they dont know any better. but thats why everyone sees the little ones and on rare ocasins a big gun will guff up but not offten and its usualy caz hes got his nose up a doe butt lol
