When the temps are falling and there is no wind, hunt as low as you can. When the wind is shifting and it is warming hunt as high as you can. I use to use a feather on floss, then went to powder, but nothing tells me where my scent is going as good as smoke from a cigar or a corn cob pipe. Actually I once had a huge 12 pointer adn a 22 inch 8 pointer come in on me when when I was smoking my pipe from down wind. The 12 gave me a chance at only 12 yards and the 8 was 12 feet. They started to square off with each other with me in the middle. There was no way I could shoot because my metal handled compound was hanging on a branch out of reach. that was my compound year, 1973. the bow was hanging because my hand was freezing and I was sick of carrying it. I moved to catch the morning sun and sit on the more comfortable side of the rock, the side with no place to hang that heavy, clunky cold bow.
