When I finally climbed into my tree stand two miles from the end of a remote Montana road late one November, snow was falling hard and the temperature had dropped below freezing. To loosen my shooting muscles and check my gear, I prepared to draw my bow a few times before hanging it on a peg. Halfway through my first draw, pow! The bow exploded in my hands and I was left holding a wind chime of bow parts. Ice had built up in the string groove on one of the cams and forced the string off the cam, bringing my hunt to an explosive halt.
