The land border crossing between Tijuana, Mexico and San Ysidro, Calif. is one of the busiest in the world. Every day 25,000 people cross the border on foot. Among the crowd are students whose families live in Tijuana. Each morning their families commute many hours to bring the children to school in the U.S.
Juan and his mom, Maria, wake up at 5:30 a.m. each day to make the trek from their home in Tijuana to Juan's high school in San Ysidro. Some mornings, crossing the border can take up to an hour and half.
