Growing up in Chicago in the early 60’s when we had a bad heat wave people would go to the lakefront and sleep out in the parks there.

Sleep outside in the summer.
Yep. We did that too.
Had hammocks with mosquito netting.
It was great too because a young person could just go to the bushes to take a pee. Our dogs and cats kept us safe from any critters foolish enough to disturb our slumber.
