A long time ago, I remember camping out at Three Forks, and was awoken by a grunting, large animal, who was beating his hooves into the ground outside of my tent as if to say...."you're in my path"........it was full moon.....it most definitely was a boar, wild pig. I often wondered about that pig.....it's one of my very favorite trail stories.
Here's a link to story about the capture of a wild pig.....click here....I'm sending you the link so that you can view the photo.
