I once went to Plymouth Rock and they had a ghost story tour at 11pm. We walked the town and the cemetary. I also did ghost tours in Savannah, New Orleans, and Gettysburgh. Ghosts are serious topics in Gettysburgh---if you ask a local adult to take you to the battlefield at night, they refuse. But if you pay a local teenager, they will take you and tell you stories that they and their friends experienced. I can tell you this---it is REALLY spooky there at night, and we heard some really strange sounds.
