Our local zoo has a vast <a href="thewilds.org">safari park</a> on a reclaimed coal mine out in the middle of noplace. They have much the variety of critters that you would expect, including rhinos, camels, and cheetah, among others. But they also have a small herd of Przewalski, and the staff regard them as much the most dangerous animals on the site. When we were there, the Przewalskis were carelessly allowed to surround the tour bus and the situation was treated as a near-emergency: half a dozen other vehicles were brought in to try to herd them away. It took a while.
