I remember staying up late Saturday nights for NWA wrestling live from Dallas on Channel 11 (10pm to midnight), KTVT. It was a family thing, we had no idea this was more or less a local-regional program. This was a huge deal back then, lol.
We lived in an old house without AC, in north Texas. We had a single water cooler in the living room and that was it.
Man, summers must have been fun back then. I live in North Texas now, and can't imagine life without it.
When I was an Army brat in Okinawa in the sixties, we lived without a/c for a time. It was freaking brutally hot. When Dad finally got us a proper house on base, we felt household a/c for the first time in our lives.
After moving back stateside, I didn't have a/c again until I was in my forties.
