The main area was a walkthrough area for petting and feeding Fallow Deer (mostly white or black variants). The deer collection also included Mule, Axis and reindeer (memory not quite serving as to whether there were any Wapiti or not). Other species included a single American Bison, a single squirrel monkey and what appeared to be a single Pronghorn, as well as goats and a small herd of Blackbuck.
This is the Grand Canyon Deer Farm, Williams, Arizona. Not a famous or spectacular place, but we'd had several excellent roadside views of Mule Deer and Pronghorn without being able to take any photos for various reasons (car surrounded by Pronghorns and the cameras in the boot being the most annoying!) so 14-year-old me convinced parents to call in here so I could get some shots. Which I did, after a fashion.
