The Ring Riding Event is the crowning contest that concludes seven days of celebrating. Colorful sports pagodas are built and spectators are lifted to their lofty perches by giraffe-necked Brachiosauruses. "Pairs of bold teenage riders, each representing a different quadrant of the island, ride Deinocheiruses, large members of the ostrich-dinosaur family - known to modern paleontologists only by their massive arms," Gurney says. "The riders' goal is to steer beneath a banner of the correct color and collect as many rings as possible."
