We are going to Toronto and on the way back we have to change planes in Chicago, O'Hare Airport. I am wondering if it would be possible to catch the train and walk around downtown for a while. Any suggestions ? Or this is total madness? Haven't been in Chicago for ages. This is our reservation( United tickets obtained with miles) Arriving Chicago 9:30 AM - Departing 1:29 PM
