I went to pig island... or whatever you call it... in the Bahamas back in October. People think these things are like friendly pets but let me tell you, the only thing they want is for you to give them food. Period. You start treating them like your dog and you'll find out real fast, like that girl did, that those animals are territorial and quite aggressive.
Many U.S. states have bounties on wild hogs and endure a significant overpopulation of these dangerous animals.
