Photos from the American Section at Azteca Stadium: Freelance photojournalist Douglas Zimmerman accompanied U.S. soccer fans to Azteca Stadium and lived to tell about it. "The Mexican fans at that point began throwing items at the American fans," he writes after the U.S. scored the first goal. "For the most part it was beer in cups that was hurled over. But different items also made their way into the section. "They included water bottles, batteries, pieces of rock and anything that a Mexican fan could possibly throw. ... After Mexico scored their second goal with several minutes left in the match, the thrown items actually increased."
