Participants hold red scarves as they celebrate the “Chupinazo” to mark the start at noon sharp of the San Fermin Festival on July 6, 2013 in front of the Town Hall of Pamplona, northern Spain. Tens of thousands of people packed Pamplona's streets for a drunken kick-off to Spain's best-known fiesta: the nine-day San Fermin bull-running festival. (Photo by Rafa Rivas/AP Photo)
