Tomorrow I'll be taking a test at McCormick Place until 5 ... so I guess Saturday would be bad since they close at 5.
I'd like to check it out Sunday ... I live in Bartlett though, so not sure if this will help you out.
You could take the Metra to Bartlett, or maybe we can find a meeting place somewhere you can get public transportation to.
Let me know, I'll check the site occasionally on study breaks...
