The Children's Museum is an awesome surprise. My friend offered us free passes as we had never been before so, we went. It is located upstairs at Navy Pier, and when we first entered the Navy Pier location, I began to fear that it wouldn't offer much as it appears to be located in a mall!! I was pleasantly surprised. There is soooo much to do and learn in the Children's Museum. The lines weren't too long and the other patrons were pleasant as we waited for some of the attractions and took turns. What a great place for children to learn about aviation, nature, gravity, water, and even archaeology. We had a wonderful day and will definately be back!!
