I forgot about the door locks freezing up sometimes. There were times when I had to heat my door key using matches, sticking the key in the lock, heat the match again, and repeat until I could unlock it. Maybe there was a efficient way to do thaw my locks, but I wasn't aware of one. But, it didn't happen often. I survived the ordeal!
uh, leave them unlocked? or were you in the bad part of Idaho?
I was visiting someone in Wyoming in the early 90s, and it was -30F at night. That was the coldest I have ever been. You learn to pack food and stuff in case you go sliding off some road in the middle of no where.
