Looking at your pictures from Ragunan Zoo, there appears to be an incredible amount of diversity in exhibit quality. The first photos of some of the bear grottos looked like what I saw recently at the closed Griffith Park Zoo (old L.A. zoo) -- that is to say, pretty bad! Then, when I saw this fantastic elevated gorilla walkway, I was so impressed -- it's totally state-of-the art! I'm looking forward to when you start your review thread from your Asian zoo trip next year!
