Chicago will be the first stop on a world tour for the IOC's 2016 Summer Games evaluation commission next spring. The fun is from April 2nd to 8th here in Chicago; the rest of the order goes Tokyo (April 14 to 20), Rio (April 27 to May 3), and Madrid (May 4 to 9). Someone's gonna have a lot of frequent flyer miles. After the tour, the commission will issue a report at the beginning of September in advance of the October 2, 2009 announcement of the host city.
