This is one of the only free zoos left in the country. Chicago's own Lincoln Park Zoo is another of course. I had an enjoyable time visiting this large zoo. They give the animals a good amount of space and try to re-create their natural surroundings the best they can. They folks who work here were friendly. I didn't get the chance to check out a 3-D film that they were showing in their theater, maybe on my next visit. You can't see everything at a zoo this size in one visit.
