NASA Great Lakes region opened up the year at the new National Corvette Museum Motorsports Park (NCM) in Bowling Green Kentucky.   The Grand Full Course was used all weekend.  This 3.2 mile configuration includes 23 turns, the Sink Hole area and a chicane at the end of the front straight away.  This challenging course was difficult for all to master.  Even those who had driven this configuration last year had a difficult time.
