Being in the tree stand an hour and 15 minutes before daylight on public land to secure a place plus beat the others no matter if zero or whatever. I moved to ground hunting a long time ago which is harder and a bit warmer plus using a hunting tent is really the way to go but I can't carry all that without sweating. Now I am on blood thinner for heart complications which makes me a wimp when it gets below 45 degrees. Do any of you have this condition & can deal with the cold with materials or type of heat packs and where to place them or anything anyone may know about. I have carried extra layers to put on when I get there but then I am like the stay puff marshmallow man and even a rifle is hard to shoulder then impossible to hold steady for when the layers tighten up. I find this important mainly because I haven't gone along this year deer hunting with either of my sons for two years now, I just hunt here on our property.
