Fantastic tour and history MJ!!! Very well done!!
I've been 3 or 4 times in the past year or two and still want to go back for more. The changes that the Zoo has gone through in the last 10 years is astonishing. The Oriental Gardens, kids play park, and the Trout River Plaza are all fantastic. And I've said this before, the Range of the Jaguar exhibit is second to none. Anyone who hasn't been to the zoo in the last 3 years is missing a lot.
The only things I see becomming a potential thorn for the zoo is the aging wooden boardwalk system and the lack of substantial expansion room. Within the next fews years the boardwalk will likely need an overhaul and without a whole lot of room to grow, the zoo may face some limitation on the types of exhibits it can include.
