Sports: Spain, Folding of The Bulls It's a wild melee when young bloods of town chase wild bulls through the streets, and are chased (and knocked down) in turn. It's an annual event that takes an amusing turn when the scramble winds up at the local bull ring. St. Fermin. Running of the bulls. Some of the bulls and some of the people slip and fall (apparently the ground is slick); a few people pile up and are almost trampled (by animals and humans).
