There's a lot more in PA than I was aware of. Somebody mentioned like 3 or 4, and none of them was the Garden Drive-in of West Nanticoke, PA. Grew up close to it. Sneak your friends in in the trunk or under a blanket. Double features on two screens.
Spring through Fall it has a decent flea market every Sunday. All the weird old shit from people's attics, not a bunch of mass produced Chinese shit from vendors.
