I was recently on a family trip to southeastern Pennsylvania, and while there we went to the Herr's Potato Chip Factory in Nottingham PA for a guided tour. This was a really neat experience. When the tour starts they take you into an auditorium and show you a little movie about the Herr family and how the business got started many years ago. Then you proceed on your way through the actual factory. This is not a simulated tour either, it is in the real factory. Your guide then shows you and tells you everything that is going on and many interesting facts about making the potato chips and their other snack products. They then give everyone in your group some warm potato chips to eat, right off the line. There is also a gift shop and a counter-service restaurant inside. It was a really fun time for me and my family. We all enjoyed it very much and hope to return someday.
