@OkapiFan Just basing that off of Google Earth's measurements, which occasionally actually agrees with what zoos report. I was skeptical but it confirms Cincinnati's total size, Indianapolis's total size, and Busch Gardens Sarengeti Safari size for example. Unless there's a hidden section that I didn't measure, I'm sticking with 25 for the main habitat. HOWEVER, counting the off exhibit spaces, it comes out to be around 43 acres.
Edit: To further attempt to enhance my case, the measuring site does agree with the zoo's report that their Elephant yards are approximately 7 acres.
