I remember something about the vet report wasn't conclusive. It wasn't even deemed 'colic', tho that was what technically killed him, and was listed, but most people think he was poisoned.
A horse that can't be beat messes up the odds, ya know.
I loved Seabiscuit, but I wished Phar Lap could get just as much publicity, but he wasn't an 'American' race horse, so not so many people know of him.
