Google's Doodle has a Chicago connection

The Doodle on the Google home page is of Wizard of Oz.  People are still trying to figure out why it's being posted today.  It is the 71st anniversary but that's kind of an odd number to celebrate.

Whatever the reason, Google now has a Chicago connection by way of the doodle: L. Frank Baum lived in Chicago at the time of publication.  According to the wiki page, "It was originally published by the George M. Hill Company in Chicago on May 17, 1900"  He also may have used the 1893 Chicago World's Fair (the "White City") as an inspiration for the Emerald City.

Pretty cool.
