Okay, rural is right, and education is poor (because money is hard to come by). I don't know about the slutty girls, because the South is also a deeply religious area. But I guess those of us from the "northern" states do tend to think of the South as culturally backwards or slow. We even had a war about that once, 140 years ago, and I think those prejudices still run pretty deep.

That said, I'm no expert, having never been anywhere in the south except the Atlanta airport and Florida (which doesn't really count, since its culture is heavily influenced by its proximity to Cuba).
