Jockey Jonatan Bartoletti of the "Contrada del Leocorno" (Unicorn neighborhood) rides Brento, on his way to win the "Madonna dell'Assunta Palio di Siena" traditional horse race in Siena, central Italy, Thursday, Aug. 16, 2007. Horses and their jockeys often tumble during the frenzied race, which pits Siena's 17 neighborhoods against one another and is a major tourist attraction for the Tuscan city. (AP Photo/Fabio Muzzi)
