USA. Sacaton, Arizona. 1999. Leonard JIM, Tohono O'Odham Indian and 10-year U.S. military veteran at the tribal headquarters of the Gila River (Pima) Reservation. The city of Phoenix, with four million people, lies just north of the reservation boundary. Modern civilization has managed in a generation or two to accomplish what the Tohono O'Odham and the Pimas could not do in 1000 years -- dry up the Gila River.
