You will always give off human scent no matter how clean you are. All you can do is try and keep down the foreign odors and some bacterial odors. I do wash myself and clothes in unscented soap but thats all. It's a waste of time thinking you will cover your scent.

I have to agree with you. Both bucks I've shot this year so far, I had to put my cigarette out before I shot. Of course, we have lots of forest fires earlier in the year (nearly every year), and people burn leaves all the time here so maybe they're just used to smoke... I don't know. While I'm sure my particular methodology won't work probably anywhere else, I really think it all boils down to being in the right place at the right time.
