September 16, 2010, marked 200 years since Mexico began the struggle that culminated in independence from Spanish rule. All over the country, celebrations commemorate this event, the same way July 4 is celebrated in the United States.
While the show in Todos Santos was fun and beyond the normal festivities, the story in Mexico City is worth viewing so check out the amazing photos from the night of the Grito in D.F.
