Photo was taken from a few steps into the United States. The arrival of U.S. National Guard troops in Arizona has scared off illegal Mexican migrants along the border as a whole, significantly reducing crossings, according to U.S. and Mexican officials. From 2006 to 2008, the Guard fixed vehicles, maintained roads, repaired fences and performed ground surveillance. (AP Photo/David Maung, File)
