A man, who plays the roll of a U.S. Border Patrol agent, examines the ankle of a tourist playing the roll of an illegal alien in a park 160km (100 miles) north of Mexico City during an excursion designed to simulate the experience of illegally crossing the Mexico-U.S. border, September 9, 2006. Locals in the town of El Alberto, some of them former illegal migrants, charge about US$15 a head to take part in the night time simulation, complete with Border Patrol agents and people smugglers.
