I have shot several deer that came in on my downwind side, while smoking either a pipe or cigar. One I was sitting on a nice soft badger dig on a steep hill side, catching some rays and enjoying a nice cup of hot Earl Grey and rather spendy cigar. A doe came down the hill straight into the wind sniffing. I carefully set my cigar down to avoid a possible grass fire, grabbed my very heavy longbow laid back and shot her at about 20 feet with the bow, arrow shelf down. Another time, the month that I hunted with a metal handled compound. Sneaking on an edge of sumac I saw the area dominant, he was heading towards me, so I skirted the ridge to get around him. I assumed that I spooked him. By that time my hand was freezing on the metal grip. so I hung the heavy machine on a branch sat down and packed my pipe with custom blend of latakia, virginia, baked burley and deer tongue tobacco. It was a damn cold morning and the smoke ran along the hill no higher than it left the pipe. I saw a better place to sit that was in full sun, I was cold. I heard a sniff and through the cedars came a nice 8 pointer sniffing as he approached, until he was only twenty-five feet away. I could not reach the hand freezing machine, when he went behind some cedars shrubs I moved to my bow and behind and upwind me stood the dominant. He saw me and moved back into the sumac sticks, the 8 that was straight downwind stepped fully around the cedars and not looking at me. That machine took a minimum of 3 seconds for me to get off a shot, the 8 pointer gave me 2 seconds at 15 feet. I could have killed either deer with any wood gripped trad bow that morning, the smell of my pipe or me had no effect on the deer, but my bare hand on that freezing metal gripped thing made a huge difference on my success possibilities.
On the other side of this, my buddy farmer was telling me how his from boots that smelled like hog poop was the perfect masking scent and no deer could tell where walked. An hour later a nice buck cutting across the disked field where he crossed with his rubber boots, stopped sniffed his foot print and bolted clear across open country until it was over the hill a half mile away. My buddy said,"Did you see that? Man I had that one wrong."
