The Fence that Floats

Riding an all-terrain vehicle, a U.S. Border Patrol agent inspects a fence for signs of illegal alterations. The unique design of the steel fence allows it to "float" atop the wind-blown sand. With the economy in tatters and security beefed up at the U.S.-Mexico border, fewer people are willing to cross illegally. Arrests in the last five months are down 24% from the same period last year.
