Three of my favorite Ohio cemeteries:
1.) Woodland (Dayton): where you can find the graves of the Wright brothers, Paul Laurence Dunbar, and Erma Bombeck. There's a statue of a dog and a boy that is usually heaped with interesting trinkets, gifts, candy, and flowers.
2.) Cavalry Cemetery (Dayton): the best cemetery hills for a runner! I almost always encounter deer, and I often see a family of red fox. Both Woodland and Cavalry have great views of the city.
3.) the unmarked graves of the former patients at the abandoned asylum up on The Ridges of Athens, Ohio, now part of Ohio University. Supposed to be very, very haunted.
