@Elephantelephant It's an amazing gorilla exhibit, but unless you attend a feeding session then gorillas are seen one or two at a time in the undergrowth. A dozen apes came out of the bushes for the 25-minute presentation.

Personally, I do not mind if I do not see any animal in the zoo, if it has excellent conditions. Visiting the zoo is about finding an animal in the exhibit and not staring at the animal in the cage as some people wish. Many people want them to come to the zoo and see the animals in small enclosures or in cages (I have even found that zoo visitors do not recognize a tiger from a lion ...). This exhibit is absolutely great.
