I love the Brookfield zoo. Last year we decided to get a membership for our family and it is such a great value, I can't beleive more people don't sign up for it. There are lots of animals to see and the Hammil family play zoo is our kids favorite part. The dolphin show is also a great attraction. This is a great place to go in the summer and if you have the membership you can go multiple times, even if it's just to walk around in the outdoors.
