Hey, I have experience along those lines! I lived in Minneapolis in the '80s. One time I was driving to meet a friend for breakfast when it was -11, and my gas line froze and car stalled in the middle of an intersection down in South Minneapolis. I walked 11 blocks to the restaurant, freezing the whole way. When I walked in, a woman who I've never seen before rushed over, put her hands on my ears, and said, "Honey, you have frostbite." Sure enough I did. So screw that! If it happened to me in -11, it'll happen to you in -15.
