I rented a terrific house on top of a ridge in Big Sur. Kids had a terrific time, Owner told us only bottles and cans went in the garbage, just toss anything edible “over the edge” where the wild boar would eat it.
Had to be careful that those horrible critters didn’t eat my two Welsh Corgis or my cat.
Hunting permits for feral hogs are not needed in Oklahoma. It is open season because they are such a problem. I have friends who have lost calves to them. So, most people are armed when in certain areas and seasons. A mama hog might have 20 piglets and they breed proficiently.
