I recently celebrated my 33rd birthday. My mom got me a terrific present. I now have a pass for the "Hidden Zoo" program that they offer. I will be taken to Mast Farm, the Zoo's off-exhibit facility for animals between exhibits, the cheetah breeding compound, and apparently several off exhibit exotic avians. I hope to see some nice hoofed stock. They mentioned zebras and tufted deer. I can only guess, but perhaps the Lord Derby eland are housed here as well and maybe even the disappearing scimitars, Mhorr gazelle, and okapi. I can't wait.
