well, it looks like it's the Alabama.....

I think it's a wise decision. She's a lightly raced filly and not a big one to boot. If she's good enough in her career, she'll have time to face the boys, but right now...........keep her with the girls. Anyway, the Alabama is a very prestigious race; I'd love to see her win it.
