As a Cincinnati transplant, one of the things I missed out on was being educated (probably during grade school) about local history. One of the things I've always wondered about is the historical reasons for the Swiss cheese-like appearance of Cincinnati. Why do Norwood, Elmwood Place, and St. Bernard exist as separate political entities?
In most major cities, you could hear an argument over whether a particular adjacent suburb should have been incorporated or annexed. But having small pockets of sovereign municipalities in the middle of a city is a little unusual, even by Ohio standards. What gives?
