You say that like rural areas don't have crop fields.

In all seriousness, I know enough about it to know it's not too different. Dumpsters and trash cans can be found anywhere for example, though they're not great sources of food in either place. I was once an anonymous rural example, but it's for that reason one could look at me and say they don't think we exist in rural areas. I was lucky enough though to couch hop. Others found solace under a local landmark, but not all rural areas have those, though they might have other things. I felt bad for one who asked me for a ride since I don't drive.
