TAPS investigates claims at the Ruff Stone Tavern, in North Providence, RI. In operation since 1792, it is the second oldest operating tavern in Rhode Island. During Prohibition, it was a speakeasy -- a tunnel in the basement (since boarded up) leads into downtown Providence. The tunnel has also led to speculation that the place was a stop on the Underground Railroad. Now, this centuries-old building is a paranormal hotspot, with claims ranging from shadows, the sounds of moaning and inexplicable fog and mist indoors. From there, the team travels to New Hampshire for a case at the Mount Washington Resort. This historic retreat, completed in 1902, has hosted such notables as Joan Crawford, Babe Ruth and Thomas Edison. In the past 20 years, staff and guests alike have reported frequent paranormal activity in the main hotel. On the third floor, guests report lights turning on and off, doors opening and closing. Objects left on nightstands have moved across the room over night. All around the building, staff members have reported frequent spots of extreme cold.
