RE: Smoking.
I used to around 15 years ago. And after I quit that, my success rate shot up. I was downwind of some guys in WV, and could smell thier smoke 50 yards away. Then I chewed cope for the last 15 years in the stand, and gave that up last year.
I think it all depends. Are the deer used to humans? Are they always around smells like that? Does and spikes will come into about anything, but you take a mature buck, I just don't think he will move if he even got a hint of a cig in the area.
