Every year around this time, our 2004 Ask the Librarian column about the best haunted houses in Chicagoland starts getting lots of hits. I just made a couple updates, but it's basically still accurate four years later. (If you don't want to travel out of the city for a fright, the Park District hosts the Haunted Sanitarium in Lincoln Park and the Haunted Beach House at 63rd Street Beach, plus Trails of Terror in Peterson Park.)
