We have been having some cold temps lately. It was -35 for a couple days and I was tired of being house bound other than hauling some firewood.....so I went out for a ski and realised that with the proper gear, I was actually sweating! It's just important to keep your face protected with a neck gaitor.......Amelia had wanted to go skiing with me but I knew it was too cold so I promised her a moonlight walk before bed. We ended up staying outside for about 45 minutes at -35 and they never complained of being cold. We went out on the river and layed down on our backs gazing up at the stars and moon and then went for a little walk out on the lake.........
