Pam mentions going to the flea market at the drive-in. The drive-in/flea market she refers to is the Circle Drive-In on US Route 6 in Dickson City, PA. In late spring/summer it is in fact a real flea market that takes places on Sundays from 7am-4pm. It's also an actual operating drive-in movie theater in April to September that shows double features on Fri/Sat/Sun nights.
Jim mentions mountain biking on Montage Mountain (now called Snö Mountain). Mountain biking is not permitted on the mountain.
