I remember NO air conditioning. I'm certain many of my older readers remember those days.
My family lived in a modest brick rancher built in the 1950's. Air conditioning was a luxury few could afford. Window fans, open windows, screen doors, and lots of ice tea was a way of life. During the day we were so busy either working or playing, I can't say I really felt the impact of the heat. When the sun was too hot to be out in it, we would lay on the cool carport concrete and play games or read books. The unfinished basement was also a safe haven. We had a little record player and lots of children's records. We'd play songs like The Bear Went Over the Mountain, lots of Disney tunes, and silly songs. One of the silliest, and therefore, favorite, was Jenny Jenkins.
