I grew up in northern Canada, snow days may have happened but most I recall is busses not running (probably not physical issue but safety issues if something happened) after -40 so little use in going to school cause least half the kids needed the rural busses to get in so teachers adjusted lesson plans accordingly.

I guess even growing up I always wished it wasn't so cold outside but the not having school days was fun to stay inside, I hated the atmosphere there but loved learning still.
