This seems to be something people don’t always give second thought to. When people talk about the homeless, the first things thought about are images of people on busy city streets in rusty clothes waiting around near allies. In there, the answer is quite static, because it can be I guess. But if that’s the case, change the setting and that changes too. In the places where I’ve lived, people often needed that mapped out. Where are they known in your rural locales?
There’s a camp in the bushes behind our local bar. The bar is near a boat harbor as well so there’s water faucets where they usually shower. It’s a relatively small camp with about a dozen or so residents.
