"Valets (pronounced VAL-its, not va-LAYS) work the four tracks in Southern California, following the jockeys on a seasonal circuit where no task -- whether folding towels, shining boots or buying snacks -- is too small to overlook. 'We're like their butlers,' Castaneda says. The valets are on the job as many as 11 hours a day, 51 weeks a year, and the jockeys come to trust and depend on them."
