Bowling Green is the place to stay. 15-20 minute drive. Call ahead and make a reservation. Check in is late afternoon. Drive in, and go straight to M.L. and get your spot, set up, sell... and maybe buy some stuff , and "then" go to your hotel and check in, when the day is done.
Bring a tarp to cover your stuff up for the night, and secure your "spot." Nobody will take anything, because everyone in Ohio is honest, ask Bicycle Larry. Go home from the swap. Some folks sleep in their trucks and vans on site. The two porta-cans make it seem like home. I love the minty smell....
