There are few things in this world that trigger a case of nostalgia for baby boomers like drive-in movie theaters. But, it isn't only boomers who appreciate these icons of entertainment; Gen Xers and millennials are packing the kids in the car or setting out for the perfect date night. Seriously, if you want to score some points with your significant other, a surprise trip to one of Pennsylvania's drive-ins would be a great departure from the same old date-night routine.

Pennsylvania was an early adopter of the outdoor movie theater craze. In April 1934, Shankweiler's Drive-In in Orefield, Lehigh County, became the second drive-in movie theater to open in the U.S. Today, it is the oldest operating drive-in in the country. The Keystone State ranks second behind New York in the number still in operation.

The evolution of technology, like the switch from window speakers to radio sound and the move from traditional to digital screens, has improved the quality of picture and sound. But the essence of the drive-in experience hasn't changed in more than 70 years - waiting for the sun to go down, the smell of freshly popped popcorn and making memories with family and friends. My own memories include taking in a movie with a carload of friends when I was a teenager and then going back to the Columbia Drive-In (no longer in operation) as a young mom with my husband and our children watching from the open hatchback of our car.
