It just goes to show the vast difference in folks when it comes to cold tolerance. I'm not as cold natured as most folks I know. But still, I'm sure I could not use those items at any where near 17 below zero. 17above, maybe, but not below.
BTW, love those High Uintas! I used to live in Layton, not far from them, and would camp up there often. What time of year was that when you and the scouts were up there? Where did you camp? Beautiful country!
