I remember one scene that cracked me up. Was back when Sherry Stringfield first left the show (to go help her sister or something in the storyline) and Anthony Edwards was running around trying to catch her before she left. They basically used it as an excuse to show just about every landmark in the city, but his route and the distance run was preposterous. Running the whole way, started at the hospital, ran to her apartment in Wrigleyville (naturally passing Wrigley itself), then back to the loop, a circuitous route to hit some landmarks (daley plaza, water tower, wrigley building, etc), then over to union station to catch her leaving on a train.
