The question of "wild" VS "feral" is a good question. They had a show on Discovery Channel and they explained how fast a domesticated hog, that gets loose, breeds out the domestic features. It was amazing. They were talking just a few generations to move from feral to wild.

The snout gets longer, tusks longer, and the hair gets more course and wire like. They also said in this show of what would happen if man disappeared off the face of the earth, that pigs would be one breed of animalthat they think would survive. Because they can adapt to almost any climate & weather conditions, they adapt to new environments, and they breed so heavy.

Its too bad you had no luck the other night. But I am sure you will score some nice pork soon.
