put the wind at your face, and do your darndest to keep it in your face. beyond that, don't smoke in the woods, chew instead if ya need something. i agree with fred asbell in that, there is a difference between a hunter and a filthy hunter, but there is no way they won;'t smell you if they are dead down wind. The only difference is how far away they will smell you. although, i gotts say, i have killed many deer right after putting out a cig. just shows if the wind ain't goin to them, they won't smell ya no matter what.
