'The best horseman that ever walked:' Billy Turner's amazing rise and sad death

The house trailer sits near a horse farm in Reddick, Florida, and inside Billy Turner waited to die. 

Next to his hospital bed were two chairs, for his wife, hospice workers and people coming to say their last goodbyes to the man who trained one of the greatest horses in racing history. 

Turner called the shots when Seattle Slew won the 1977 Triple Crown, and he remains one of only 11 trainers to win the Kentucky Derby, Preakness Stakes and Belmont Stakes in the same year.
