Here's some more information on the new playground, the most recent time I was at the zoo, it seemed virtually finished. If you look closely at the picture in the link, you can see plants on the playground structure, if these plants were to grow out, I think it will look pretty nice and naturalistic.
Animals Exhibits Elinor Friend Playground
Their chimpanzees are in a concrete hovel. Their polar bears are in 1930s era grottoes. Their big cats are in a 1930s era decaying box. They have spent 3.2 million dollars on a playground. ANOTHER playground. They have no discernible plan to build actual new animal exhibits to replace the 80 year old decaying zoo.
Unbelievable.
Yet, there it is, and after watching this zoo steadily decay for the last few decades, I guess one has to believe it.
