Right now, Bill Turner is the only living trainer of a Triple Crown winner. His horse, the great Seattle Slew, was undefeated in nine races, a streak that ended with his Belmont Stakes win in 1977. Bill might lose that distinction June 7, if Big Brown takes the Belmont, but for now the reporters are still dropping by his barn in the mornings, asking whether he thinks Big Brown will win, or just collecting memories of that past Triple Crown campaign.
