I went to Chicago for 16 days in September 1999 and what a
FAB time I had. Got my Airmans certificate from Du Page Airport (for free from the FAA!). I did all my flying in a AA-5 from Chicago Midway. The particular aeroplane came 2nd in Oshkosh the year before for it's paint job (bright orange with black dots - just like a Cheetah).
As I recall the landing fees were very expensive (certainly for US rates anyway) at Meigs so I only went in once - after approaching in Flight Sim for all those years!! Left base to 18 is great though, straight towards all the buildings.
Students aren't allowed to fly in there though. There are a number of other accidents too caused by overshoots/undershoots into the water. I understand this has contributed towards its threatened closure.
Did you visit the John G Shedd aquarium just at the end of the runway? Quite good. As you said, Michigan Avenue is very cool too.
