It took two days on the bus for Catalina Cespedes and her husband Teodolo Torres to get from their hometown in Puebla - Santa Monica Cohetzala - to Tijuana. On a bright Sunday in May they went to the beach at Playas de Tijuana. There the wall separating Mexico from the United States plunges down a steep hillside and levels off at the Parque de Amistad, or Friendship Park, before crossing the sand and heading out into the Pacific surf.
Sunday is the day for families to meet through the border wall. The couple had come to see their daughter, Florita Galvez.
Florita had arrived that day in San Ysidro, the border town a half hour south of San Diego. Then she went out to the Border Field State Park, by the ocean two miles west of town. From the parking lot at the park entrance it was a 20-minute walk down a dirt road to the section of the wall next to the Parque de Amistad.
