Here's a Haunted Houses of Metro Detroit advertisement from the WRIF's Inside Out magazine Halloween edition in 1990. I picked this up somewhere for a buck since that's what written at the first page. The listed attractions were as follows: WRIF Haunted House (Farmington Jaycees), Brighton Haunted Barn, Barnstormer Dungeon of Doom (Whitmore Lake), Bloomer Haunted Forest Walk (West Bloomfield), Haunted Museum (Toledo), Haunted House (Hazel Park), House of Nightmares (Warren), Haunted Barn (Wayne), Mutillation Mansion, Warren Goodfellows Haunted House, Vampire Vault (Taylor), Spooktacular (Utica?). More highlights to come from the magazine.
