Phoenix, the capital of Arizona, is now a city of 1.6 million, the fifth most populous in the United States. It sprang to life over 150 years ago with the arrival of the pioneers, who built irrigation canals to make the land fertile.
Despite its location in the Sonoran Desert – which stretches across the U.S. southwest and into northern Mexico – Phoenix has become a favorite place for retirees, attracted by year-round sun and its ochre mountain backdrop.
For those who can afford it, there is air conditioning. A Major League Baseball game is played early in the afternoon at Chase Field, where a retractable roof and air conditioning keeps the stadium a cool 64.5F (18°C).
But for the homeless population of Phoenix, there is no such respite.
