Iconic stadium. You can fly into Chicago rather than Detroit with lots to do in Chicago. The Pirates are playing the Cubs at Wrigley Field on Friday afternoon so we'll take in that game and head to Ann Arbor late that afternoon. It's a little over a 4-hour drive from Chicago to Ann Arbor. Two classic stadiums in the same trip.
As someone else pointed out, the Rose Bowl is nothing special but the tailgate experience on the golf course surrounding the stadium is fun as the UCLA fans were very cordial.
Haven't been to Lincoln but Omaha is nothing special.
