Love the skyline in the pics. What was you and your son's favorite animals at the zoo? My kids go crazy for penguins and monkeys, I can't pull them away.
I didn't have a clear favourite, but Miles was a huge fan of the Snow Leopard (he bought one from the gift shop) and the giant Anaconda.
If you look beside the opera house in the middle photo you'll see a huge cruise ship - this meant the Zoo was filled with loud and enthusiastic American tourists. ("Look there Stan! That Kangaroo's got a Joey! Oh my Gawd!!"
It added to the general atmosphere.
