Chicago layover

After getting only a couple of hours sleep Tuesday night we headed to the airport for our 5:45 am flight to Chicago, arriving there at 8am.  That gave us MANY hours for a layover before heading on to Beijing at 7pm.  So we made the most of it and took the metro into the city to do a little sightseeing.  We had some authentic deep dish pizza, toured Millennium Park and the original library now turned museum and still had 3 hours before our flight.  The following are just a few pictures of our day in Chicago.
