Even if your Scooby sense doesn’t feel sudden cold spots at the bottom of the stairs or unseen fingers clutching at your throat, a ghost tour can be an info-taining way to take in the history — or legend — of a city. I’ve taken numerous ghost tours in my travels — the best combination of story and storyteller was a Key West tour, hosted by a man whose gravelly voice could be mistaken for Robin Williams, but far scarier. The variety of spooktacular ghost tours held in the Washington area provide the ghost-hunter and the skeptic alike an opportunity to learn more about what some say is one of the most haunted cities in America.
