RE: Smoking.
I'm sure they smell it and most of the time don't like it. Everybody has a story of a deer they saw while smoking or drinking coffee or something, but it's the deer they don't see that's the problem. I'm a half a pack a day smoker and I leave my cigarettes at the cabin when I go out bowhunting. Gunhunting's a different story. Most of the deer I see are running from another hunter and don't have time to wind me anyways. Also I'm just not as passionate about gunhunting.
