How? At the heart of Riggs' tale is not a quest, but a tour. As a roadie his job was to construct the arena experience, as a rock crusader it's to take that experience and use it as a battering ram. He does so by recruiting a following - from those he has liberated and those he has dazzled into submission. And so the headbangers you free from a mine (they were using the aforementioned banging to dislodge rocks from buried hot rod parts) join your traveling show to help 'convince' further metal-loving stereotypes into helping you.
