Big Brown: Behind the Scenes

Trainer Rick Dutrow Jr. (top right) looks on with another trainer as his horse works out at Belmont. The three-year-old is undefeated in his first five races. Big Brown's foot specialist Dr. Ian McKinlay (bottom left) and co-owner Mike Iavarone (bottom right) also watch closely. Iavarone feels confident about his horse's chances. "I don't think you can predict anything in horse racing. They're not machines, they're four-legged animals," he said. "But if there's ever a horse I'm going to go out on a limb for it's going to be Big Brown." ( Meena Hartenstein/ABC News)
