“The feral swine are a non-native species suspected of escaping from game farms”
What the heck is a game farm?
A place for the kinda hunter who likes shooting fish in a barrel.
Las vegas
A place where they breed and release or import and release game animals for people to hunt. Hunters pay to hunt the land where they game has been released.
If a hunter goes pheasant hunting on non-game farm private land or on public land, the hunter may or may not even see a pheasant. There may not even be any pheasant there. If the hunter goes to a game farm, there will be pheasant there.
Game farms also import exotic game from other parts of the world for hunters to pay to hunt.
A lot of hunters don't consider this to be “sporting”.
