Well, I smoke, and I smoke on stand. Still manage to kill a couple mature bucks each year, and a handful of does. I don' t use any scent lok or anything like that, I just wear rubber boots that are stored in a tupperwear bin, and sprayed down with carbon spray before I walk in. I' m sure being fanatical about scent helps, but it' s not something I bother with, too much work for me. I just hunt the wind religiously, and will walk two miles out of the way to come in to my stand in a way opposite the deer. I won' t hunt a stand if the wind' s not steady and in my favor.
I won' t tell you smoking doesn' t hurt your chances a little. But I' ll be smoking this coming season, and I' ll be killing a few bucks and a bunch of does.
