Post #51 gave a good idea of what a "canned hunt" area is. They had similar problems in Arkansas a few years back, and such nastiness was outlawed there, as well. Then there was the celebrated Jimmy Houston canned shooting up north, which was discussed both here and at THR. But these were anomalous events, and have been dealt with.
As for the YO, it's much smaller than when Capt. Charles Schreiner first took up some half-million acres. When Charley III was running it as a hunting ranch, it was down to some 50,000 acres. The gate lock's combination was changed every month, starting with .25-35 and going on up to .45-70.
Two of Charley III's ex-wives had an antique store in Austin. They both agreed, "I love him, but I just couldn't stay married to him." They'd both go to the ranch as hostesses for gatherings there. Bobby Snow was ranch manager, back then. His wife had a couple of cougars and a couple of jaguars in a little zoo-llike deal. Hal Matheny, Jerome Alexander and a guy nicknamed "Buttons" were hunting guides there.
So, yeah, I know a little bit about the YO. Charley's dead, now, though, and I've not kept track since they started selling "ranchettes" of a hundred acres or so.
The YO was instrumental in the beginnings of exotics in Texas. They had Sally the eland, who browsed on scrub-oak leaves. Blackbuck antelope and Axis deer. Even a Himalayan mountain sheep (goat?) which could stand flat-footed and jump some eight feet. There was also a sizable herd of longhorns.
But, yeah, orchidhunter, tell us of your eyewitness account of somebody on the YO shooting an animal in a 100'x100' pen. If you didn't see it yourself, or personally know the observer as a reliable witness, don't try to feed us any more non-factual nonsense.
