The massive machine bore down on them. Nearly fourteen feet long and six wide, it seemed to completely fill the bridge. Almost a ton and a half of wood, glass, rubber, brass and steel, a monster, roaring and trumpeting as it approached its kill, the great shining black fender arches framing its huge goggling eyes. The thrusting tusks of its sprung-leaf suspension threatened to skewer any soft flesh and young bone that lay in its path. Black smoke billowed from its rear. Sparks spat from behind its grille. No dragon of ancient legend could have seemed more terrifying or more deadly.
