Canfield Speedway

Canfield Speedway is a half mile dirt oval racetrack that hosted (major) sanctioned auto racing from 1950 to 1964, but other associations ran until the late 1970s. There was also a 1/4 mile dirt racing surface that shared the front stretch with the 1/2 mile track. It was used until the track was closed to auto racing in 1973. Attendance varied from 30,000 people for larger events to 10,000 people for ones of less significance. The track is located at the Canfield Fairgrounds in Canfield, Ohio, and is still in use today, primarily during the Canfield Fair. 
History.

It was Charlie that had close ties with Johnny Marcum, (MARC) Midwest Association of Racing Cars and Canfield Speedway was the priority track. In 1964 ARCA took over MARC as the desire for dirt tracks died out.

Bill Rexford.
Bill Rexford won the inaugural event (later known as the Poor Man's 500) and went on to take the Grand National Championship that year in 1950. He was the youngest diver to win the championship in what is now the NASCAR Cup Series. He was aided to the championship when Lee Petty was stripped of some points for racing in non-NASCAR sanctioned events. His only lead lap finish in his career was at Canfield Speedway (when he won). His only career pole came at Canfield Speedway the following year in 1951. He was the 1st of 6 drivers to win a championship without winning a pole in that season.
