OCTOBER 9, 1979.  IMPERIAL BEACH, CA.  "Boundary of the United States"  People in Playas de Tijuana, Mexico look through the border fence an ecumenical group conducting a ceremony in Friendship Park.  The scene was peaceful and calm and I didn't see anyone slip through the very porous fence line.  Erected in the mid 1800's, this solid marble obelisk 200 yards from the Pacific Ocean is the western most of 258 monuments that mark the nearly 2,000 mile boundary of the United States and Mexico.
