Our guide, Marshall deserves 6 stars! He was patient with our group, personable, upbeat and provided a great overall experience. Since we are all locals who decided to be tourists in our city for a day, we asked Marshall to show us something we haven't seen, and while touring up the lake, through the museum campus, he led us through Northerly Island, south of the concert area through the park/nature refuge created by architect Jeanne Gang after Richard M Daley bulldozed Meigs Field airport at that location. It was the highlight of our experience. Marshall is a great tour leader, making us feel safe as we navigated the area, crossing LSD and numerous pedestrian and bike paths. Two members of our group of four were totally scared of getting on a Segway and both had a wonderful adventure and would do it again.
