Organizers change it up every year to keep visitors on their toes. Previous year's themes include : Haunted High, Haunted Hotel, Sinister Stronghold, CarnEVIL of Fear. This year the theme is Night Terrors. You can find the haunted house at 150 1st St NW in Harmony. They open for the season on October 17th and admission is $10 per person. That money goes to support the arts at Fillmore Central.
