When I first heard about the Indian rhinos arriving, and then thought about the master plan, I was thinking the very same thing. With rhinos being one of my favorite animals, I really hope they stay; come to think of it, it would be kind of a waste to bring in a major animal species like these rhinos for only a couple of years when their exhibit would get replaced by something else anyway.
And two more points:
1. I say the Indian rhinos should replace the takin in the master plan.
2. In the Asian Highlands, I noticed that while sun bears are a planned species, there's no exhibit for them on the map! What up with that?
That master plan does look spectacular, however, and as soon as every part of it is complete, nothing will stop me from taking a trip to Omaha.
