"Since 1873, the temperature in the Twin Cities has remained at or below zero for at least four consecutive days a total of 28 times, with the most recent occurrence being a four-day stretch ending February 15, 2021. There was a five-day stretch ending January 18th, 1994. The longest such streak on record was seven days, from January 1-7, 1912."
So? And by the way, it's standard time in the winter when they are getting home in the dark so year round DST would give them another hour of daylight to get home but wait, then they would have to leave home in the dark. Poor kiddies having to endure traveling in the dark. Too bad you can't just get your sun to shine longer so the kids won't have to deal with the dark. Oh, well man has been dealing with the dark since he stood up and started walking around and apparently the kids have managed to make it pretty well as we have overpopulated the world.
PS: my mother traveled 11 miles one way to a school on the south plains of Texas. She did have the luxury of doing it in a horse drawn hack which she described as something kind of like a buggy. No heater like today's school buses of course, just quilts and blankets to stay warm. She wound up with frost bit feet one winter. Yeah, it get cold down here too and everyone can come up with a sob story.
My mother and aunt rode a horse to school, in good weather when they were still down in Amhearst , Neb., a bump in the rode in the middle of Nebraska, and for a bit when they went to country school after moving to Minnesota, so what you tell me is nothing new. (My aunt used to ride a horse in parades when she go older with those fancy Roy Rodger type stirrups.)
Now that record I copied is from the Twin Cities, now a heat sink, i.e. always warmer than surrounding country, especially than upstate 70 miles North where I am in now.
The Twin Cities have never had -40 in my life time, we have had it where I am now several times in the past 30 years, -30 is a bitch, -40 is a bitches mother.
Way up North, where the sun sets 25 minutes earlier than where I am now and you think the children should get used to it, -50 is not uncommon.
Until you have spent at least one day walking two miles in -50 degree weather, which I had to do one day when I was in school up there, you have ZERO idea of what a true hard winter is.
It can kill quickly , and has in the past.
Trying to find information about Mn weather that is not based on the heat sink Twin Cities is pathetically hard but here some thing from the DNR.
