Um, Columbus is the 12th-most populated city in the US. Cincinnati (go Bengals!) and Cleveland (which, I'm told, rocks) are major cities, too. Dayton draws people from both Cincinnati and Columbus (not to mention being home of the Motel Beds, for all you kids who are on their nuts--and I'm not criticizing).

By the way, Ohio, the best state of all (well, probably not--but it's from where I am), is the seventh-most populated state in the U.S.

And, I could name you a ton of bands with Ohio links. Guided by Voices, the Breeders, Afghan Whigs, Ass Ponys, etc. etc. etc. etc. etc. etc. etc. etc. etc.
