FASCAR Pro Truck and Sportsman Series: The FASCAR Pro Truck and Sportsman Series is a pickup truck racing series that takes place in the Florida area.  It was established by the "Florida Association of Stock Car Automobile Racing" organization as a developmental "stepping stone" for locals with an interest in stock car racing.  Drivers have used this series to better prepare themselves for the NASCAR Sprint Cup Series in addition to the Xfinity Series and the Camping World Truck Series.  The typical age of a driver in this series is between 16 and 18 years old.  Most races take place in oval tracks.  Warm temperatures year round translate into tough and treacherous races.  This series has operated in three race tracks: Columbia Motorsports Park (1/2 mile), New Smyrna Speedway (1/2 mile), and Orlando Speedworld (3/8 mile).

Cobe Trophy Race: The Cobe Trophy Race was an automobile race held in Indiana, in 1909 and 1910.  The trophy was named for, and donated by, Ira M. Cobe, president of the Chicago Automobile Club.  As one of the first long-distance races in the area, it was billed as the "Vanderbilt of the west," a reference to the Vanderbilt Cup Race, which had been held in Long Island, New York since 1904.  The first running took place at the Crown Point Road Race Circuit, in northwestern Indiana.  For the second year, proposals were submitted by the Indianapolis Motor Speedway and by the Elgin Road Race Course, just west of Chicago.  Ultimately, the Board of Managers of the Chicago Automobile Club decided to make the 1910 race a speedway event, rather than a road course contest, and hence the second race was run at Indianapolis.  At the time of this decision, the Club also announced the intent to bring the race to the Chicago area in 1911.  As it turns out, though, there was no Cobe Trophy race in 1911 or in later years.  Only two drivers competed in both Cobe races, 1909 winner Louis Chevrolet and his teammate, Bob Burman.
