RE: smoking in the stand
I have quite a few members at our club that smoke while they hunt. You can still climb trees and find butts wedged in between the bark of the trees.
I wish they would bag thier butts but more than often they leave them in the trees!
To answer your question all of these hunters nail deer. Now, remember they are pretty high in tree and this may help with the deer not locating a direction?
I don't smoke, and if I did I personally wouldn't smoke in the woods.
KEEP HUNTING THE GREAT OUTDOORS & GOD ALIVE, PASS IT ON!
