On your Texas 60,000 acre high fence pen. The animals largely com from zoos and circuses and are bred on the ranches themselves or by breeders who sell the offspring to the ranchers. When the zoo animal gets too old, it becomes a target. To each his own, but I think it is pathetic. If you did not know this, just google "hunting zoo animals in Texas". You'll also read how important this is to conservation, which is bullshit to me. They're conserving them so some lazy hunter can kill them for a meaningless trophy.Where in America are people hunting zoo animals?
There are some game parks in Africa which do a good job culling populations, selling hunting licenses, using the money toward conservation. Most are just as corrupt as everything else in Africa. I've been to a couple dozen of the game parks there, but never wanted to hunt. I've also read all the Peter Hathaway Capstick, Robert Ruark, and Roosevelt safari books.
