Per their tradition, fans poured over to the Angel of Independence on Sunday to celebrate Mexico's 5-0 Gold Cup win over the United States, which considerably raises the stakes in the rivalry before Aug. 12's World Cup qualifying match at Estadio Azteca.
The scene was heavily policed and rowdy. People spontaneously decided to do a long victory lap around the monument, some bikers came through to burn fuel and tires, and then weirdly, an especially energetic contingent of Ámerica fans showed up -- even though Ámerica lost in a match with Chelsea that day.
Here's a clip I shot in the crowd just before a downpour of party foam. Mexico, by the way, hadn't beaten their rivals on U.S. soil in 10 yeas, since March 1999 in San Diego. A popular chant at the Angel: "El que no baila es gringo! El que no baila es gringo!" (Roughly, "If you don't dance you're a gringo!")
