Formerly the Rosemont Horizon, this large arena is used mainly for DePaul basketball games, large musical events and conventions. The parking is well known for its near misses with O'Hare-bound airliners, and the roof actually collapsed during construction. The acoustics aren't great either.
It's the home of the minor league hockey team, the Chicago Wolves. Tickets for their games range from $8-$30; call 1-800-THE-WOLVES to purchase.
