i have smoked on stand before but i try not to make a habbit of it. If the winds are right i might have a smoke but otherwise i wont. As far as sent, i have come to believe that if all you want to do is kill a deer and the size of it doesnt matter then i wouldnt even spend the extra money for scent cover.As most of the younger deer are curious and will give you a shot. especially if you are gun hunting and are capable to take a longer shot. On the other hand if you want to better your chances of harvesting a more mature deer you need to pay attention to your scent. Chances are if your smelling like campfire out in the middle of the woods your not going to see the better deer in the area. You may see deer, and alot of them at that but you will most likely not see the trophy you want. And if you do happen to see that monster, i would rather be scent free to better my chances of him coming into range. Remember the better part of hunting is being in the right place at the right time. I dont want to be in the right place at the right time and not get a shot because im wearing the same coveralls that i wore around the camp fire the night before.
