 This Traveltalk visit to California starts by asserting that somewhere in the state, one can find the climates and cultures of people from all over the world. It starts in the southern desert area, on the border with Arizona. Modern irrigation methods are used to make vineyards and date palms grow in this otherwise inhospitable area. We then go to actor  Leo Carrillo  (qv) s ranch and end our visit looking at Chinatown and the Olvera Street neighborhood in Los Angeles.
