What is there to do in Chicago?

[damaticous]

I'm in Chicago this week for Symantec Enterprise Vault training. Actually I'm in Oak Brook, but it's a suburb of Chicago...about 30-45 mins West of downtown.

I'd don't like driving in cities too much (ok, I'm not a good driver in cities) but would like to site see a little bit since I'm here.

I will be going to Naperville to meet and eat dinner with my Tigerdirect/Global Computers rep tomorrow.

I'll have most of Friday afternoon to go site seeing and was wondering what you all would recommend?

Thanks in advance
