I saw him several times run and win at Indy, back when it was called the "US Nationals" (prior to sponsorship).
I've been past his place many times in Whiteland IN. He was a farmer that had a penchant for racing, and it took over his life.
There was a time when he was unbeatable; 10 championships (most or all in Fords, which was a big accomplishment back in the day).
