[Chicago] Suggestions for things to see in Chicago

[Michael Weigend]

Thank you, Atul, for your suggestions for things to see in Chicago.
I am a German Pythonist stopping by in Chicago (30.6. - 2.7.) on my way from 
a conference in Boston to some friends in Cincinnati, profiting from your 
knowledge about Chicago ...

Regards
Michael
