i know its hard to hunt in the cold wearing tight pants, so a heater and blind are a must, lol. seriously, regardless how cold it is, you should be moving, from stand to stand, from truck to stand, etc etc, you will be warm, sit into a spot that gives you a good 360 vision if possible, matching your camo, call until you get cold, then move again to the next. 30 min. and move 30 min. and move.
