On a sunny day we decided to stop at the zoo. Little did we know so did all the local schools for the end of the school year. The zoo is so large that this did not seem to be a problem. This zoo is well spread out with many different animals. The only thing I did not care for that some of the exhibits you had to pay extra for so I felt 'nickeled and dimed" by the end of the day. Overall, I would say put this on your list of things to do in Milwaukee!
