As darkness creeps across city streets, Grim Philly unearths Philadelphia's grisly past with a pair of highly researched, carefully developed twilight tours rife with sinister themes and risqué adult content. Professor Joe Wojie—a regular lecturer on historical and macabre topics at Rider University in New Jersey—leads each two-hour odyssey, peeling back the corners of local folklore with stories and facts drenched in blood or terrifying amounts of grape jelly. In addition to its original Vampires, Sex, and Ghosts! tour, Grim Philly serves up spooks with Cemetery, Serial Killers; Blood & Beer!, which whets appetites with gruesome tales of gangsters and psychopaths before stopping at Mexican Post Tavern for beer and snacks. No matter the tour, guests are ensured to pass a number of historic sites, such as Benjamin Franklin's grave and the street corner where Paul Revere ate an entire horse.
