I started with the E-Cigs just for hunting 2 seasons ago. Ended up switching totally to E-Cigs and now I'm off everything.
I've seen plenty of deer while smoking in the stand and the same with E-Cigs. Here on LI they are so used to people that none of that scent stuff seems to matter anyway. I hunt in regular camo clothing, rarely spray down and hunt in all kinds of wind and I see plenty of deer within range.
