From eastern Pennsylvania boundary, (ie., the city of Philadelphia) is only about 50 miles (about 81 km) from the Atlantic Ocean (for example, Atlantic City, NJ). Naturally, it would depend on from where in Pennsylvania one is traveling--the state is 170 miles (274 km) north to south and 283 miles (455 km) east to west. Also, if the scenes were actually filmed in PA, it's possible the shore you are seeing could be that of Lake Erie, as the state has 51 miles (82 km)of coastline along the lake, and 57 miles (92 km) of shoreline along the Delaware Estuary. Lake Erie comprised about 750 miles of inland area in Pennsylvia; the lake is the tenth largest in the world.
