Revelers sleep on the ground during the early hours on the third day of the San Fermin running of the bulls on July 9 in Pamplona, Spain. Pamplona's famous Fiesta de San Fermin, which involves the running of the bulls through the historic heart of Pamplona for eight days starting July 7th, was made famous by the 1926 novel of U.S. writer Ernest Hemmingway called 'The Sun Also Rises.'
