When cold weather arrives, I find two things that help me greatly.
#1 I take plenty of time to get to my stand.
We all know to dress in layers to help stay warm, but if you leave the house too late, you'll hurry to your stand and work up a sweat......which is bad news after about 30 minutes.
#2 My feet are always what get me. I learned a little trick this year while on stand. When my feet start getting cold, I flex my thigh and calf muscles over and over, which I think helps blood flow to my feet and toes....or maybe it just tricks me into thinking I'm warmer, either way it works!
