Told a story on here a few years ago. My buddy who lived in Flagstaff at the time(60,s) told the story of a livestock truck that turned over down there during a blizzard, hundreds of pigs went loose. Arizona residents were given deprevation tags. These things eventually became ferrel after a few years and started populating. Randy showed me a picture of his brother and himself sitting next to 4 - 1000lb dead pigs, he said his dad and sister had also killed a few. He said they had ham and bacon to last for years!😆 He showed me pictures of the damage they were doing to some prime mule deer / elk habitat. They were uprooting boulders the size of Volkswagens! Super pigs, I believe it.
