a few years back (about four, when I was fourteen), I did not pay much attention to scent or anything. I was real green when it came to bowhunting in general. With that said, I used to sit around a campfire on our annual trip to the milk river with all my clothes on. To the best of my knoledge, it did not detour deer, and I saw plenty. I do not know if that is because they were so plentiful, or because the smoke smell did not bother them. I do not do it anymore, but I had luck and saw great bucks, with smoke as an "unknown" cover scent.
