Didn't use this. I'd like to go back and look at this again and at some of the books that come up when you search on "walking chicago". We walked a whole lot in the city (even more than planned when we got lost on the way to the Museum of Science and Industry) The Loop walk contains some interesting stops, but there are a lot more stops that I would make. Probably a good book for planning your own walks, even if you don't use it specifically.
