First, tragedies like Eight Belles’ death are an inherent part of horse racing. They can’t be entirely prevented. Riding horses under any circumstances can be dangerous. When he first became acquainted with my quarter-horse Rusty, my farrier, an outspoken individualist like many people you meet around barns, warned that he was too headstrong and athletic for a middle-aged novice.
“You keep messin’ with that big sumbitch and he’s gonna hurt you” was how Tom put it.
Problem was, I’d already bought him. Not long afterward, I’d saved Rusty from a near-fatal colic attack on a 104-degree July day. It’s hard to describe my emotions when he stopped while I was walking him out—he’d been staggering, in a daze—to nibble on clover. He was going to live. He drank something like eight half buckets of salty water at half-hour intervals that night, roughly 150 pounds of lost fluid.
