Yes, 8 below Tuesday at dawn, my first hunt day. We won't start until about 9 or so. High of 10 above that day and better the next 2 days.
We'll be ok if it doesn't get windy. A few years ago I photographed Great Gray Owls in northern Minnesota. We went out pre-dawn each of 3 days at 40 below zero. We were dressed for it and never got cold for more than a few minutes one day. There was almost no wind which made a huge difference. The wind forecast in WY is for 5 to 10 or so each day. Fingers crossed.
