why is everyone so against the utili-trees? They are one of the most innovative concepts for an elephant exhibit I have ever seen. Sure, their ugly, but they are so useful to the elephants, and the whole goal of the exhibit was more so to keep these elephants active than immerse you in an Asian forest.
Actually, the primary goal of the exhibit (at least as stated by SDZS) is to show how elephants and other animals lived in North America during the Pleistocene. A cartoonish set of animal sculptures next to giant metal "utilitirees" and a massive, unadorned concrete holding building are unlikely to allow visitors to feel transported back 12,000 years.
That said, this is clearly a huge leap forward in terms of elephant well-being and care at San Diego, and that is a very good thing.
