We spent 8 days visiting Chicago.

We spent 8 days visiting Chicago. We choose the Paul Wolff Campground about 22 miles out from Chicago center.  From there we were able to take the Metra system into Chicago's Union Station which is about 10-15 blocks from Navy Pier and the waterfront area. We bought a 5 day GoChicago pass for each of us which we downloaded to our smartphones. These could be scanned at each activity/event in lieu of printing out tickets. The first two days we took our bikes on the Metra to get around the city.  The second two days we purchased a two day Water Taxi pass for navigating the city. The water taxis were definitely more fun and were a little easier to use than the bikes but we were limited to their routes. All in all it turned out to be a good way to tour the city and we had a wonderful time. Chicago is a very interesting and vibrant town. We're glad we took the time stop even though we were somewhat fearful of doing in/from an RV.
