Nogales, Arizona.USA.October 20, 2006..A cross marks the death along the USA border fence as many illegals die trying to enter the county. The port of entry to the USA is near by. The city is divided between Nogales Mexico and Nogales USA. The fence extends for several miles in either direction off the port of entry - then there is little to stop people from crossing illegally. Nogales is flooded with Mexicans legal and illegal and is mostly a transit and shopping town.
