Some bulls are wimpy and get no respect from cowboys because they don't buck well enough to earn good scores. Others are so powerful and unpredictable that riders hate to draw them, because they know there's a good chance they'll get thrown. A perfect middle animal gives you a wild ride but still gives you a chance to stay on board. Mister USA, a yellow, flat-horned seven-year-old that jumps high and then typically turns back hard to the left, has that rep. He lived up to it again at this year's National Western Stock Show, where both his riders managed to stay on and earn high scores: 94 and 87, respectively. A native of Utah, Mister USA contributed 23 out of 25 points to each ride. And, no, he's not done yet.
