Harlem Rocker?

i saw today that the canadian bred harlem rocker opted out of the preakness for canadas version of the kentucky derby. his owners hope he will win canadas version of the triple crown. i really dont know anything about canadian horse racing but when was the last time a horse won the triple crown up north. could you imagine big brown wins the triple crown, harlem rocker goes undefeated and wins the canadian triple crown.then they face off in the clic. that would be monumental. and ya i know im getting waaaaaaaaaay ahead of myself
