My mom says one of the houses she lived in as a kid, between 1955 and 1965, had an outhouse. This was in suburban Ohio.
When I was in Girl Scouts in the 80s we not only had to USE a latrine but CLEAN the latrines before we left camp. Not clean the waste bit, but make sure the seats were clean, eradicate bugs and cobwebs, and sweep the floor. It sucked but it sure beat having to do our business in the wilderness!
This summer I went to a little get-together at a shelter on my friend’s grandpa’s farm. The shelter decent, like you’d see in any small-town park. I guess when they use the shelter for big events they rent a Port-O-Potty. But for our get-together, we had to use grandad’s home-made latrine. It was a “two holer.” From what I could tell, the holes led down into the Cuyahoga River. I manned up and used the thing twice rather than go home early.
