Erebus is a four-story 100,000 square-foot haunted house attraction in Pontiac, Michigan, open only on Halloween. From 2005 to 2009 it held the Guinness World Record for biggest haunted house attraction. The attraction opened its door in 2000 in an abandoned parking garage by Edward and Jim Terebus. Their events change from time to time but the main theme is sending patrons by scientists through time to different eras of history. They create scary situations by using actors, props, animatronics and huge puppets. In one of their big events, a six-foot dragon comes from the fog and eats the patron. Some of the other events use mirrors, a moving wall pushing patrons into a bottomless pit, or burying them alive. Erebus is not recommended for children under the age of 13.
