We sure did Shmoops.
My trip has been Indy, South Bend and Chi-town. Wife planned it out. I seriously would have preferred to come see you Shmoops by doing Milwaukee and Chicago instead but I'm still trying to figure out what my wife was thinking when she chose Indianapolis over Milwaukee.
As Shmoopy mentioned, Museums, Navy Pier (spent about an hour there yesterday), Millennium Park (the Bean). Did the Chicago River Architecture Boat tour last night, which was excellent. Probably hitting the Willis Tower (formerly Sears tower) today and seeing some of the different neighborhoods in around North River. Wrapping it up by taking my son to the Cubs game at Wrigley on Friday.
