Every Wednesday, on the Somorrostro beach, not far from Frank Gehry's Goldfish, a group of people sweat it out on the sand. Curious onlookers think that they are a group of friends playing with a a frisbee. Truth is, this group takes it seriously. A few years ago Barcelona saw the birth of its first ultimate frisbee team. The sporting discipline was born in the 1960s in the United States and revolves around these stylishly designed discs. What for so many people is a simple game is an important part of others' life. It also transmits an interesting set of values, as it is one of the few sports in which there are no referees.
