You need to check out the Nashville City Cemetery. I know, cemeteries are kind of off-limits. But not this one. It is historical and has a walking path through it. There's a Pokemon Go gym in the middle and at least 20 Pokestops along the path. The only down side is parking. You'll have to park in a neighboring business lot so Sunday afternoons are a good time to go. Have fun!
