OK, sorry for being a week plus late, but I've been there and I've seen it now.
First of all, this was my first trip to the OKZoo. And yes, I was impressed. Like Fort Worth, it is a complete zoo, but unlike Fort Worth, it doesn't feel like it is falling apart due to age and neglect. The apes are done well enough, I really like their cat collection which have some good and bad, and think OK Trails is VERY impressive, except for the lasrge fence along the back of the bear exhibits. Anyone complaining about Dallas' fence in Giants needs to re-examine this, because it is implemented in a worse way. That said, OK Trails is pretty great, and the zoo over all is very complete. When Asia is complete, I'd like to see the middle of the zoo hollowed out, including the pachyderm house for a new African area.
But. you're all here to hear about Asian elephants. In short, it's good. Three large yards, with water in each. the two smaller yards are obviously not lived in at all and the patches from grass can still be seen. The way it works is you have a path you follow between the yards, which for now kinda loops around and sends you right back out where you came in ala OK Trails. For some reason, they decided to send visitors 30 feets into the air on this path giving an areal view of the exhibits and the barn. The barn, btw, goes up against the path, and has a giant glass window to peer into. Not much to see other than the main "lobby" area between different stalls. The area is huge, especially for 2.5 elephants, and more members are needed for this herd. The two they have look quite small up in the air with the amount of space they have.
Then there's the show. The auditorium is a basic concrete pavilion area and it works. The show has a lot of basic behavioral paths, but I'm not a fan of some of the things shown, like having the elephants walk across the logs, which I felt was a bit too circus-ey. If one of them were to fall, this zoo would be hurting. There is a powered gate between the demo area and the main yard. That said, this is a solid exhibit, it needs some time for the elephants to move in and make it their own, as well as some additional elephants. This is designed for 6-8, and it needs 6-8. I hope it holds up well over the next few years.
Oh, one last thing. When I went it was during my spring break from University of North Texas. Seems OKC breaks 1 week later. Also the weather all day was about 40 degrees. In other words, I was freezing and had the zoo to myself. So, yeah, there was that.
