In 1981 when I was just out of boot camp and waiting for BE/E school at Great Lakes, IL, we had to patrol the base for I think it was 4 hours. It was -80 F wind chill factor. I thought I was going to die. I can't imagine being somewhere where the normal temperature on a given day is that cold. The wind chill must be unbearable to be outside for long.
