From parades to eating contests to dances, Cinco de Mayo has become an adopted holiday for many Americans. In Mexico City, re-enactments of the Battle of Puebla, which the holiday is in celebration of, take place. Mexican-Americans may also use the day to show off their culture, while others may celebrate it for more light-hearted reasons -- such as a burrito contest complete with sombreros.
