Manistee's Ghost Ship Every autumn, the S.S. City of Milwaukee transforms from a National Historic Landmark vessel to a frightening Ghost Ship. A twenty-five minute tour lures visitors through a haunted maze of catwalks and pipes in the engine room, and narrow passageways and spooky cabins in the upper decks. http://www.carferry.com From: Haunted Attraction Directory/ USA (All 50 States)/Michigan
