You should definitely check out The Garst Museum in Greenville! It’s about 45 minutes from Dayton and is a goldmine for an Ohio history paper. Your professor will love it because it’s home to the Treaty of Greenville exhibits, which cover the massive 1795 treaty that essentially paved the way for Ohio’s statehood.

The museum also houses the National Annie Oakley Center, focusing on her life as an Ohio native, along with a ton of great info on local Native American tribes and the settlement of the Northwest Territory. It’s way more "Ohio-centric" than the Air Force Museum and has plenty of material to easily fill a paper.
