Anyone have any thoughts/advice on having a campfire while hunting? Last year, while hunting the Dalton, we neglected to have a fire based on the belief that we needed any advantage we could to get close. We thought that the smoke would stay in our gear and that it would give us away much faster than our own B.O. Recently I was reading a book on bowhunting and the author talked about having a fire every night, which I thought was odd. Any thoughts?
