It's late morning by the time they even leave the school, after which, they:
****spoilers***
1 - Drive downtown
2 - go to the top of the Sears Tower
3 - eat a fancy lunch
4 - attend a baseball game
5 - go to an art museum (where they clearly take their time)
6 - do the parade
7 - pick up the car
8- take the friend to the park overlooking the lake
9- drive back to the burbs
10 -go swimming
11- try to 'fix' the car
12 - walk home
Longest day ever
