In this photo taken Tuesday Oct. 2, 2012, is the preserved office and library of the farmworker leader Cesar Chavez available for viewing in the visitor center on the property where the late farmworker leader once lived and worked in Keene, Calif. Today, the foothills of the Tehachapi mountains continue to house the United Farm Workers of America headquarters and memorials to Chavez, though farmworkers no longer live there. President Barack Obama is designating parts of the property as a national monument and visiting the site on Monday, a move seen as likely to shore up support from Hispanic and progressive voters just five weeks before the election.
