DEL MAR, Calif. - Ivan Puhich was not looking to go back to work five years ago. He had been on the racetrack since 1944, with time out for a stint in the Marine Corps at the tail end of World War II, and was content to enjoy a semi-retirement, gabbing at Santa Anita's Clocker's Corner in the morning, hanging out at the track in the afternoon. All the fun of the races, with absolutely none of the pressure.
