I've posted my memories of the Summer of 56 that I spent on the South side of Chicago with my jazz loving cousin many times, highlighting various aspects of that visit. I would like to post another aspect of that visit.
I liked to go for a swim in Lake Michigan every day, but someday's it was way too cool; one dip in the water and you got chill bumps.
My cousin liked to entertain in the evening, and he didn't have AC; he just opened a window and everything was fine. I don't even recall any noisy window fans.
When I strolled Cottage Grove in the evenings, I needed a sport coat or a sweater.
Sometime in the 80's, many people in Chicago died from heat stroke because they did not have AC. No one had AC in 56 because they didn't need it. Climate change has been happening for a long time, but no one called it that.
