Maybe global warming is reversing again. In the late 60's I was in Minot ND, 50 miles S of Canada. I put a 6 pack out on the window sill and it froze in 5 minutes: -30F. So I love the pic 66.
Back then the polar cold always dipped down to freeze the Mid West. In 65, I swapped out a Chevy 2 speed auto (outside up on jack stands) one night in January in Omaha Neb and it was -10F. I had to rush inside to thaw my face evry 15 minutes.
The same winter, walking hoime from my paper route, I passed a slow walking cat in a field. The next day I saw the cat about 10 yards farther, standing frozen in its tracks. Serious cold and very hardy people. Very tough on cars. In 69, I was discharged in Minot, I had to have my car towed a gas station to thaw it out inside the heated garage for a few hours to start it.
