Built in the 1920s, the former tuberculosis sanatorium "is abandoned and dangerous. There are still beds and equipment inside. It looks haunted," Hauck says. The place has spawned "lots of negative experiences with ghosts, (including) poltergeist activity where things are thrown at people." Most of the activity is on the fifth floor.
Devil's DenGettysburg (Pa.) National Military Park
This formation of giant granite boulders was the site of a fierce and bloody Civil War battle. "There's a lot of electromagnetic and voice phenomenon here," Hauck says. "It's one place I go and really feel something. It's not scary, but it's unusual. There's lots of energy." It's just one of many haunted spots in Gettysburg, Hauck adds. "Almost anyone there has a ghost story to tell." 717-334-1124; nps.gov/gett
17 Hundred 90 InnSavannah, Ga.
The inn, which bills itself as the city's oldest, is said to be haunted by a heartbroken woman who jumped from a third-floor balcony in the early 1800s as her lover's ship sailed out to sea. "I've talked to tourists who have seen her," Hauck says. The ghost has plenty of local company, Hauck says. "Almost any house in old Savannah has people talking about ghosts." 912-236-7122; 17hundred90.com
Fire Station No. 2New York
The station on West Third Street in Greenwich Village is said to be home to the ghost of a fireman with salt-and-pepper hair who wears an old-fashioned helmet and a red shirt. "We call it a lepke — an apparition that looks so human you think it is, until it walks through a wall or something," Hauck says. "People will go up and talk to him, and he disappears."
