Ive heard of the rear boar sightings.
i believe since they are non native, it would be open season all year. If you see one i think you can shoot it, as long as its in a place where its legal to shoot. the ones you would find there are escape convicts from a preserve or someone had one as a pet etc on there personal farm and it managed to get loose or it was let loose.
they wont last up there, you would need some forest gump pure sht luck to get one. the reason is, if there is one seen wondering around someones going to get it, think about it, as soon as it goes into the wrong yard and starts wondering around for food, someone going to look out there window say What the? a Boar!!! Bang dinner!
same with the mountain lion tails, tracks or sightings. i don't think they are really truly there. when seen or a paw print found, i think there escape convicts also. they probably came about in rear sights because someone had one as a pet somewhere up there and it got to big, so they just let it go. same with a wolf sighting, probably someones pets at one time.
most of the guys who have shot a boar loose in Maine NH Vermont, they all say a guy down the street used to raise them, or a fence fell down at the preserve that's a few miles from there home. everyone that Ive heard of being shot had got loose from somewhere or another.
