Just got back from Hershey, put it this way it was not worth the parking fee, but had to pick up a order. Looked like a homeless camp with tarps covering everything!
I remember going there as a kid. Swap meet was in the fields that is now far end of park before they built the Wildcat. Often it was a mud bath. And it was packed anyway. Wear a raincoat and mudboots and git er done!
