It seems to me this writer may have never set foot on a "haunted" attraction and was just trying to find something - ANYTHING - from Michigan to complete their list.
Its darkened cobweb filled wood rafters filled with items straight out of 1941 are enough to give you the creeps but add in the fact that the latched door continues to be found open is down-right chilling.
We are blessed in Michigan to have one of the premiere Haunted Attractions in the United States. The Jackson Underworld Extreme Haunted House opens for the season This Friday Night September 9th in Jackson.
