If you are an antelope here you are relatively lucky, but boy there is a load of crappy enclosures here. Certainly worthy of the title of biggest roadside zoo...
@Ituri yes, there are two lobes off to the right and left of the pool/waterfall. The pool is kind of in the middle of the exhibit, the sides have natural dirt and turf as well as shade. The habitat is pretty long, but not that deep. Here are two pics from @snowleopard that show the two sides, you can make out where the pool is in the second picture.
