We didn’t have A/C when I was in school in the early 80s and our school only had 3 black students.
I went to school in Mississippi in the early 60’s.
We didn’t have AC or black students..............;^)
I lived in the south in the mid seventies. Our elementary school had A/C, but the middle school didn’t. If the temp got too high they sent us all home.
My eighth grade homeroom was never less than a steamy 82 degrees the entire year. The room next door never broke 58 during the winter months. What else do you expect from gubbermint union employees?
