No clue. What else are Thoroughbreds for, except racing, though? I mean, why would one want one, except for, um, hunting to hounds, steeplechasing, or racing? And even those are, I think, subdivisions among thoroughbreds -- I think the spindliest legs are the straight racers, rather than the steeplechasers or hunters.

Read that Jane Smiley book, Horse Heaven! It's a really good saga. Kind of (I can't believe I'm saying this) Black Beauty for grown ups. Except that book grated on me, and Smiley's doesn't.
