"Unidentified migrants, who did not wish to give their names, from the state of Jalisco, Mexico, cross the waters of the Rio Grande, with the help of two ""coyotes"" or  smugglers, in an attempt to reach the U.S. border, in Nuevo Laredo, Mexico on Wednesday, May 18, 2006. Migrants preparing to cross the border in Nuevo Laredo said they would prefer to climb walls than make dangerous trips through the desert into Arizona and New Mexico, routes that have become popular after U.S. authorities made it tougher to cross near San Diego and El Paso, Texas.
