I was in college in 63. It was -10 at Wittenberg and we still had classes. Went home after finals on a train to Akron where the temp was 26 below and 2 feet of snow. The newspaper said to keep the front page and show it to your kids the next time they complain.
-20 tonight in Mpls./St. Paul, and that’s an improvement!
I remember it being about that when I was in college in South Dakota in the 80’s. Classes were never cancelled.
My son’s H.S. classes were cancelled for the last 2 days in MN. We did get to -30 below though. The school bus’s probably wouldn’t have been much use with diesel fuel.
