Ok time for me to be a dumb tourist from the Northeast...I'm going to Chicago for 2 nights, 3days next month and I was thinking about doing some railfan related things. I was thinking abour riding the EL, seeing Union Station, maybe going to the Museum of Science and Industry (also reccomended by non railfan friends). Anything else? Good Metra commuter line to check out? I assume getting to the Ill. RR museum sans car is out of the question?
