The AMA National Motocross Chamionships return to Pala Raceway following a four-year absence—after Glen Helen Raceway dropped out in a contract dispute. The last time Pala held an AMA National was also because Glen Helen refused to sign its 2010 National contract. Pala held Nationals in 2010 and 2011 before the race was moved to Lake Elsinore, where that National also only lasted two years. Now, Pala is back on the schedule under its new name, Fox Raceway. Take a lap of the track.
