If you still don't have Halloween plans, then buy two tickets to the Houdini Seance Spookapalooza at this theater, the oldest in Decatur. The event embraces the spot's scary past: Ghost researchers love it because it was built on the site of a devastating fire in 1916, and a ghost named "One-Armed Red" still walks across the stage. Other apparitions have been spotted in the stairwell and lobby.
