@Ituri: would you say that the Asian Highlands section of the zoo is the best part of Hogle? It was built in 2006 and seems to have a strong theme to it...
Yes, Asian Highlands is absolutely the best exhibit at the Hogle Zoo. The theming is well done and the exhibits are beautiful. It is also well positioned in the zoo at one of the highest points providing nice views of the mountains in the background, and there is something symbolic about climbing to reach the Asian Highlands exhibit to see rare and beautiful cats.
