RENO, Nev. (AP) -- Cows 1. Former San Francisco 49ers' quarterback Joe Montana 0. Taking part in a cutting-horse demonstration Friday to help kick off the 1999 Pacific Coast Cutting Horse Association Derby Classic and Challenge, the four-time Super Bowl champ proved he can ride a fast-moving, quick-turning cattle horse. But this time the cows were just a little faster. The object of the competition is for a horse and rider to ``cut'' a cow out of herd and keep it from returning. Montana got interested in cutting in 1994, watching friend and former Kansas City Chiefs tight end Jonathan Hayes compete in Fort Worth, Texas. ``I thought, ``OK, it'll probably be fun to watch, but it was a lot more exciting than I even imagined,'' Montana said. ``If people like horses at all, once you've tried it, you're hooked.'' -=-=-
