I know the feeling. 2 years ago in the Black Hills we had -32 and our helmets froze to our jacket collars. We were so damn cold we didn't turn our heads, just lookin straight down the trail. It was suppose to be a 20-30 min. ride just to check out the trails. A wrong turn, 2 hours and the entire loop later we were back at the cabin with an 1/8 inch of frost on our helmets. All the booz in the cabin couldn't warm our bones that night. Man the sleds ran like champs that night though!!!
