The Raceway will mark 43 years of historic racing action in the Sonoma Valley during the 2013 season.  Opened in 1968, then-Sears Point Raceway was constructed on 720 acres of property that was a working dairy farm in the early 1900s. The facility hosted its first official event, an SCCA Enduro, on Dec. 1 of that year. Since then, the facility has grown to 1,600 acres and expanded into one of the premier motor sports venues in the country, hosting 340 days of racing activity each year, including the NASCAR Sprint Cup Series, NHRA Full Throttle Drag Racing and the IZOD IndyCar® Series.
