Residents of Naco, Arizona join residents of Naco, Mexico for a volleyball match every year during the fourth "Fiesta Bi-Nacional" at the fence that separates the U.S. and Mexico.

The two communities used to be one with people passing freely across the road, but that all changed years ago when a 13-foot-high border fence formally split Naco's US and Mexican sides.
