I had a friend who shot a moose once. He was standing in the tree line smoking a cigarett and the moose walked out about 50 yards from him. He said the moose just stood there looking at him. go figure.
Hunted in a camp with a fellow who would hang his clothes out side so no smoke from the wood stove would get on them. Said it would scare the deer. One evening he came inside wearing his undies and smelled liked he had been smoking. I asked him if he smoked while on stand which he did. Asked him why bother with his clothes. Didn't see him kill a deer either! Who can tell!!
