Wow.
I love the show.
I remember hearing stories of one near where I live. It was either in the Tunnel Mill, State Park or Ammo Plant woods...Clark County, IN. I want to say I have heard it was registered? Not sure what that means.
That's a cool site. I'd never heard of the sightings in my area, and I've even hiked, camped, and climbed/rapelled in the areas where they occurred.
