In short, you really don't expect change at a zoo, it's hard to justify to your mid twenties self why paying $16.50 to see something you already have is worth it. You go to see animals, and you see animals. Sometimes you see overpriced ice cream cones and the occasional child screaming in horror, the later sometimes being a plus.
And then you go to the orangutan exhibit.
Now, what is a natural habitat for an orangutan? Trees, surely. Some vine like constructions that they can climb with. Rock ledges for perching purposes.
And, oh yeah, burlap sacks that they can use to pull over their heads while smashing their face up against the viewing windows.
It's debatable on whether or not $16.50 is worth paying to see an orangutan imitate a hobo, but it was surely the highlight of my day.
