About an hour north of Philadelphia, [Shankweiler's Drive-In Theater](http://www.shankweilers.com) is America's oldest drive-in, having been in continuous operation since April 15th, 1934. From April through September, the theater offers al fresco moviegoers first-run programming at rock-bottom prices: just $9 for a double feature. Plus, you can order from a snack bar with a throwback menu that includes funnel cake and cotton candy.
