"Joe Leonard was the AMA Grand National champion in 1954, 1956 and 1957 before retiring in 1961 to concentrate on cars, and Gurney gave him a shot in 1965.
At Langhorne, Kenyon crashed and was knocked out as his car was engulfed in fire. As he sat slumped in his burning roadster, Leonard jumped out of his damaged car and pulled Kenyon to safety.
In 1968, Leonard won the pole at Indy in Andy Granatelli's turbine and was nine laps away from victory when his fuel pump broke.
He was snapped up by Parnelli Jones in 1971 and scored the first of his back-to-back USAC titles. For 1972 he was paired with Andretti and Unser in the Firestone-backed Super Team. Pelican clinched the crown with three races to go."
