We didn't have any in NYS until capitalism overroad wisdom...
"Where Have Feral Hogs in New York Been Spotted?
New York State documented four herds located in Tioga, Cortland/Onondaga, Delaware/Sullivan, and Clinton Counties. Escapees from wild boar hunting preserves are likely the source of some of this population".
Not enough guns in the State to keep up with wild pigs mating unchecked. I'm presently in Germany where hunting wild pigs (boar) is in focus because of disease that spreads to domestic pigs (Schweinepest)... but it hasn't put a dent in controlling the population... they're wandering around in cities where they can't be shot at...
It's "drive hunt" season now... chasing them out of the woods and cornfields with dogs... so I guess I'll be back out in the woods again soon to continue doing my part to "assist"...
