Urine is something i never did until my uncle tom made me do it one day and i had a 10 point run up right under my tree stand so I do it almost everytime i go huntin now. The doe urine is a key when getting that big buck because if you've got the right scent on (as uncle tom says) "Boys with this stuff you just might get raped by a big ol buck." The bucks smell the doe urine and they come to it its just simple as that I dont really know the mechanics of the whole thing but its always been a plus for me. Also cover scent is a very very key item to have in your garb belt or bag. I always spray myself down and my buddies down throughly right when we get ready to go to the woods. Also you always need to make sure that you really get the bottom of your boots covered so that the deer can't smell your human stench all the way up your tree or shootin house. I mean i'm no master hunter or anything but these are just the little things that i make sure that I do. A good doe bleat is also a good thing to have. But what else you got on your mind? anything i can help with I will do my best
