Here's a vintage brochure for the long gone Old Chicago in Bolingbrook Illinois. Old Chicago was a indoor amusement park and shopping center.
Now only if it was a shopping center first and amusement park second, much like the Mall of America, maybe Old Chicago would have lasted more than six years (1975-1981).
Maybe it's just me, but there's something fundamentally depressing about an indoor amusement park.
UPDATED FUN FACT: A memorable scene in Brian De Palma's The Fury (1978) was shot at Old Chicago. If you watch the trailer below at around the 1:10 mark you'll see a spinning ride go out of control, and send its passengers sailing through a large glass window.
