Right you are, Mr. Bruce. Graham Hill is the only driver to have completed this particular trifecta of race victories. Indy in '66 (compare his comments in the winner's circle--"I'm a bit surprised to have won"--to today's "the Tampax Tampons/Coca-Cola/Preparation H Chevy Lumina was really running great on its Goodyear Eagles" pre-prepared speech); Monaco in '63, '64, '65, '68, and '69; and finally Le Mans in '72, teamed with Henri Pescarolo in a Matra (where, at age 43, Hill hobbled around the pit lane like an old man, to the consternation of his teammate, then jumped in the car and proved as fast as just about anybody there).
His son Damon won an F1 World Championship for Williams.
Thanks for the kudos, Bruce. Carson Rose and her mother are both doing well.
