I met Bobby Frankel in the 1976-77 at Santa Anita before he became famous. For a while he ran a handicapping breakfast and it was fun and informative.
Frankel requested that in lieu of flowers, donations be made to Old Friends Retirement Home, the Grayson Foundation, and CANTER, an organization to find homes for retired horses.
