Well time to show the result of Justin's "mistake".  
We had both hoped to be able to put the incident behind us and enjoy the rest of our trip, but fortune just would not smile on us. I found out that there is a Medieval Times restaurant in the Chicago area, however all the shows were sold out for the time that we were there. One of our primary plans for this trip was to visit Fermi Lab. However, we discovered when we got there that their website does not accurately describe how tours are handled and we missed our only chance for the month of June. Furthermore, we were outrunning bad weather on the way out, and left early to get ahead of more thunderstorms on the way back. All in all, we didn't really accomplish much. On the bright side, we did spend a day in downtown Chicago (more pictures below) and saw the Art Institute and the Adler planetarium. We played a couple of nice rounds of disc golf, did some fun geocaches, and ate at some nice restaurants. (Of course, those stories have their own details of mosquitos and free meals -- ask me about it in person someday.) The best part, of course, was that we were together away from home and having fun. I'd do it again if given the choice. ;)
