This looks like an interesting little zoo. How is the trout exhibit? (#43 between the ruffed lemurs and the prairie dogs) That's something that you don't see in a lot of zoos.
It interests me that Puma concolor is described as Mountain Lion, a name that I've never heard anyone in the UK utilise. It's always been "Puma" to me and always will.
To be honest, I don't remember much about the trout exhibit - just a basic 'fish farm' type pond I think - similar to, but smaller than, the one at Birdland: http://www.zoochat.com/482/aviary-trout-lake-birdland-19-09-a-106640/
You're right, it is a very basic square fish farm type pond, much smaller & less attractive than the Birdland one! It can barely be described as an exhibit
I found this strange when I first visited about 7 years ago, they are still persisting with it though!
