Thousands of people gather in Pamplona, Spain, every year for the Festival of San Fermin. The nine-day event kicks off with a carnival, fireworks many bullfights, and of course, the encierro, or "running of the bulls." As our colleague Alan Taylor writes:
Held since 1591, San Fermin remains a popular, if also dangerous and controversial, event: Several people have been injured already this year, and the festival continues until July 14.
