this cold front should have all things looking for food, was a high here oif 10 degree's and very windy, wind chills should have been crazy low today here

as for boot blankets, I have a few pair they make a BIG difference if you ask me, BUt I have also found they can work even better if you remove your boots and just stick in DRY socks and a heat pack, they work like a sleeping bag then
I think when your boots are off you get better blood flow or??

plus if you use the arctic shield brand one's they have that heat reflective material in them that works off body heat reflecting it back, like a space blanket then

hand muff's help too on these cold days!
