As someone who is living there right now, I don't think that is an accurate depiction of Ohio unless you are way outside of a city. Columbus for example is basically a 10 mile circle of sprawling suburbia centered by a relatively small downtown. Your statement is analogous to saying California is just hundreds of miles of hills and mountains and forests while discounting the major epicenters that exist.
This is what I meant. For example, the entire corridor from Cleveland to Canton is a sprawling series of small towns with no beginning or ending. Reminds me of driving down the 101.
