Buy a ticket and join the fans at a game at Rent One Park. If there's nothing happening while you're in the area, you might like to check if the stadium offers a tour of the facilities.
This sporting facility in Marion comes recommended by many travelers, so leave a spot for it on your must-see list. Don't think that's all there is to do here, though. There are loads more places waiting for you to experience after Rent One Park. Crab Orchard National Wildlife Refuge, Kokopelli Golf Club, and Williamson County Fairgrounds are not far away.
