Good thing about having a young person visit: we walked!
After a movie at Clark and Diversey, we went to Uncle Julio's Hacienda. I would have walked over to the red line and taken the train 2 stops. We walked instead - 37 minutes.
Another day we walked to Shake Shack, then to the John Hancock Building, then to the Chicago History Museum. 4 miles! We took the bus home.

I walk a lot in the city but mostly a mile at the most, about 20 minutes, at one time. This has been a good reminder to go the distance.
