That's how it was in the '70s. The winter of 1972 was when we found out that you really can stuff a dozen kids and one adult in a small car and drive to school (highly illegal of course, but the alternative would have been that all of us would have frozen if we'd had to walk, as we had the farthest to go).We often get worse snow and cold than anywhere in the UK in Edmonton, but I've only seen the schools close twice here in my lifetime - for teacher's union strike actions.
When I was young, they just made us bundle up and trudge to school like Antarctic Explorers.
It's -17C here now; -26C with wind chill. If the manager's offer of a space heater is still good, I plan to take him up on it.
