Eight seconds does not sound like a long time until a two-thousand-pound bull is trying to throw you off its back. In rodeo's rough stock events, that is the whole contest: stay aboard a bucking bull or bronc for eight seconds, one hand in the rigging and the other in the air.

The rules are unforgiving. Touch the animal, the rope, or yourself with the free hand and the ride is disqualified. Come off before the buzzer and the score is zero, no matter how spectacular the effort. Make the whistle, and judges score both the rider and the animal, rewarding control, timing, and the sheer difficulty of the beast beneath.

That last point surprises newcomers. Half of every score belongs to the animal, so a rider who draws a lazy bull is capped no matter how well he rides. The best cowboys want the rankest stock, because only a hard bucker offers the points to win.

Eight seconds demands a strange blend of strength, balance, and calm under chaos. Riders describe the good ones as almost quiet, the body loose and reactive while the mind stays a half-beat ahead. Then the buzzer sounds, and the hardest part begins: getting off in one piece.
