Dayton

Dayton needs 1 day: touring the National Museum of the United States Air Force, the world's largest military museum and free to enter, with over 350 aircraft on display, on the same afternoon you can also visit the Wright brothers' bicycle shop, where they developed the plans for the first airplane before testing it in North Carolina. April-June and September-October bring the mildest weather. It's inexpensive for Ohio. It's the hometown of the Wright brothers, considered the inventors of controlled powered flight, and also of over 60 inventions registered with the US Patent Office, including the cash register.
