For this thread, I want you to name the zoo that in your opinion, has made the most improvement on itself. You can also count zoos that are well in progress of improving.
For me from what I have visited, definately Central Park. I was never there when they had cages and lions, but my grandmother has told me of a few stories
My experience is very limited, but any time Lincoln Park Zoo puts it's mind to updating one of it's older exhibits, the new one is always always miles ahead of the previous. I still have vague memories of the old concrete Large Mammal and Great Ape houses before the renovations in the early 2000's, both of which were incredible improvements upon their predecessors.
Although I've only visited it once, I would suggest London, because it has come on leap and bounds since it opened .
