Heh heh, with all the races they're running here, it's no surprise that a few mishaps happen along the way.  If you look around the Shimmering Flats then you'll see evidence of past crashes -- scraps of rocket car parts are littered everywhere!$B$BAnd those parts are worth money to the gnomes and goblins.  They're always looking for more contraptions to slap onto their cars.$B$BSo go out and get me parts.  Bring me a heap and I'll pay you well.
