Jan 31, 2009 -- PHOENIX, AZ: Traditional Nahuat (Aztec) dancers perform a blessing at the Macehualli Work Center. The Macehualli Work Center in north Phoenix opened six years as a city of Phoenix supported day labor center. The work center is now privately owned but still supports day laborers who congregate in the area. Many of the center's clients are undocumented immigrants. The presence of the undocumented immigrants has made the center a flashpoint in the illegal immigration debate in Phoenix. Photo by Jack Kurtz / ZUMA Press
