** FILE ** The international border line made up of bollards: irregular, concrete-filled steel poles, seperating Mexico, left from the United States are shown in a Feb. 17, 2006 file photo inside the Organ Pipe National Monument, Ariz.  Sixty three miles of vehicle barriers are in place on the Arizona border and authorities look to have a total of 200 miles of barriers across the Southwest, mostly in Arizona and New Mexico, by the end of 2008.
