These do better in the cold than the ones down south.
Winters have been keeping the other ones from moving up.

Domestic pigs are weird because in just a few weeks of being released into the wild they go completely feral.
Domestic pigs also interbreed with wild boars at a rate dramatically greater than feral domestic dogs, wolves, coyotes, jackals, and dingos do in the wild.
