Lonely Planet has a good article about a California Vacation, though I think they may have forgotten there's a Southern California with some cool sites as well. They did cover several of my personal favorites of California: Redwood National Park, Yosemite National Park, Mendocino / Sonoma Coast, San Francisco, and Point Reyes National Seashore. However I'm not sure it's fair to ignore several other treasures of California such as Sequoia Kings Canyon National Park, Lassen Volcanic National Park, the Missions of Southern California, Hollywood, Disneyland, and much more.
