I once worked for a cell phone company that I swear they used a map from the 1800's in that Ohio was considered the midwest of the country. So that would have made the South Central US Alabama and Georgia.
It's true, Ohio is still considered the midwest. Which I (living in NE Ohio) don't get at all, since we are right next to PA and NY, which to me makes us NE US. Also, we are right on Lake Erie, so to me we are North Coast. But several companies I work for refer to Ohio as a midwestern state...oh well.
