Hartcreek,
Hogs are an invasive species, and most states treat them as varmints with a policy aimed towards erradication, even though none have been successful.
Of those links you provided, I did not find where any of them require you to consume feral hogs. I did find the one for NY to be amusing though.
New York wants to eradicate all Eurasian boars in the wild. To achieve that, the DEC had to ban the hunting of Eurasian boars.
It takes government to come up with that kind of logic.
Anyways, having said that, I can't imagine shooting one, and letting it all rot without using at least some of it, though trying tp process them by the truckload (Old Stony) does not look like fun.
There are pockets of them in Ohio, but you chances of finding and getting one are pretty slim, so if I ever do have success, I'll butcher it for sure. I got one, a young boar about 30 years ago, and it was truly amazing on the table. Cut it into steaks and roasts. It tasted like domestic pork, but had almost no fat. I'd imagine, like every animal, where you take them, and what they've been eating makes ahuge difference.
