RE: smoking in the stand
In my camp, we have one or two members who smoke, and they seem to be able to kill deer, consistently. I was hunting once with a guy who lit up a doobie on stand when a 3-pointer showed up, and he was a bit upset that he had to put the pot out to shoot the deer. I've also heard that some successful hunters smoke cigars on stand; deer are curious animals, and they feel compelled to find out what that strange smell is.
Personally, I don't like smoking; but, hey--if you want to do it, that's fine with me. I have asthma, so even if I wanted to, it wouldn't be a thing I'd take up.
