Hot topic on a couple forums - here is my responce from another forum:
I live a few miles from the ones in Cortland County. A few are shot every year as targets of opportunity in the 4 week (not 2) gun season. Still so rare and move enough so trying to target them is pretty much a waste of time. Most of the local landowners are pretty fed up with those trying to "help with the problem" without bothering to ask. I haven't heard of any granting pig only access - those who are seeing them are taking care of it themselves or the ones hunting there are doing it.
There has been no significant increase in sightings or kills since a couple years after the 1st ones.
