          | The 
            finish gates are positioned along the edge of a five-foot vertical 
            dirt ledge that empties into a gentle down hill slope. Tim attempts 
            to push Chris across the remaining 15 feet. His initial effort is 
            unsuccessful. Chris climbs out and Chris and Tim begin tossing small 
            stones from the path of the vehicle. Chris returns to the controls. 
            The Official announces that 30 seconds remain on the clock. Scully 
            works at it until the rig begins to move. 15 seconds remain on the 
            clock. The vehicle builds momentum. |  |
