Ed Oswald: My granddaddy used to work down there. One time, him and two of his buddies broke into a whole new cave system. Really big. Company bosses figured there should be some rick picking to be had, so they sent my granddaddy back down to have a look-see. He never come back. Folks reckoned they must've broke clean through into hell. The devil was mighty pissed.
