A couple of people approach the wall on Tijuana-side of the Border Field State Park fence, which separates the cities of San Diego and Tijuana at the US-Mexico border going three hundred feet into the Pacific Ocean, on August 12, 2012 in San Diego, California, at the launch of "caravan for peace" across the United States, a month-long campaign to protest the two countries' brutal drug war. The caravan departed from Tijuana with about 250 participants and is due to end in Washington on September 10. AFP PHOTO / Frederic J. BROWN / AFP / FREDERIC J.
