Yes, the little black pig runs all over the place around here...a regular icon! To my knowledge, he is harmless.
There is also a BIG red boar mama with a big litter of piglets in the area, too, though they tend to stay deeper and South of Trinity. Cute little buggers, but I have't seen them in a couple weeks, so those babies might be "biggies" by now.
There have always been wild pigs, coyotes, lynx, and an occaisional bobcat spotted right here in our area. I don't know of any instances ever occuring with any of them.
