Cincinnati has an interesting "culture", or blend thereof, being a few miles from Indiana and across the river from KY. You hear a lot of different accents there.
Atlanta of course seems to be mostly transplants from Ohio and Michigan plus a lot of Hispanics. Part of the town is heavily Vietnamese populated and they have some good places to eat. In the park near us, one can see just about every kind of person and accent, even some French speaking folks at times.
