I happened upon a notice in the job listings on the AZA website. An exotic game ranch in (or near) Austin, Texas is developing a new public drive-thru safari called The Savanna. Not much detail given, just that they have a lot of hoofstock and will be obtaining a greater variety for their new park. A google search did not bring up any listings. Perhaps someone out there in Texas can fill us in?
I will have to follow up on this. The Austin area would be perfect for this. I will see what I can find out.
Although not the proposed "Savanna" park mentioned in this thread, this link provides a succinct history on the little-known Austin Zoo: New day for the Austin Zoo
