California: the Dream and the Challenge in the Twenty-first Century
"California is more than a geographical or political state. It is also a state of mind, a way of life, and an evolving dream. The Governor asked noted author and State Librarian of California, Dr. Kevin Starr, to prepare a special essay on the Golden State, placing in context its history, culture, and people with the challenges and dreams of the new Millennium."

California as I Saw It
"Full texts and illustrations of 190 works documenting the formative era of California's history through eyewitness accounts. The collection covers the dramatic decades between the Gold Rush and the turn of the twentieth century. It captures the pioneer experience; encounters between Anglo-Americans and the diverse peoples who had preceded them; the transformation of the land by mining, ranching, agriculture, and urban development; the often-turbulent growth of communities and cities; and California's emergence as both a state and a place of uniquely American dreams."

Anza-Borrego Desert State Park
"With over 600,000 acres, Anza-Borrego Desert State Park® is the largest desert state park in the contiguous United States. 500 miles of dirt roads, two huge wilderness areas (comprising 2/3 of the park) and 110 miles of riding and hiking trails provide visitors with an unparalleled opportunity to experience the wonders of the Colorado Desert. The park name is derived from a combination of the name of Spanish explorer Juan Bautista de Anza and the Spanish word "borrego," referring to bighorn sheep. The park features washes, wildflowers, palm groves, cacti and sweeping vistas. Visitors may also have the chance to see roadrunners, golden eagles, kit foxes, mule deer and bighorn sheep as well as desert iguanas, chuckwallas and four species of rattlesnake. "

With over 40 miles of trails, boating on Lake Murray, camping at Kumeyaay Lake, numerous informative hikes, and a state-of-the-art Visitor & Interpretive Center, Mission Trails Regional Park has something to offer everyone." - located between Santee and La Mesa, where people go to climb Cowles Mountain for a breathtaking view of the region.

Torrey Pines State Reserve
"Torrey Pines State Reserve is located within San Diego city limits and yet remains one of the wildest stretches of land on our Southern California coast! Because of the efforts and foresight of the people in this area, 2000 acres of land are as they were before San Diego was developed -with the chaparral plant community, the rare and elegant Torrey Pine trees, miles of unspoiled beaches, and a lagoon that is vital to migrating seabirds. One can imagine what California must have looked like to the early settlers, or to the Spanish explorers, or even to the first California residents here, the Kumeyaay people. There are 8 miles of trails, a visitor center, and guided nature walks on weekends and holidays." - a rare treasure, hidden in the urban metropolis.
Torrey Pines Association
"The Torrey Pines Association was founded in 1950 to encourage public interest in, and support for, the preservation of the rare Torrey pine trees and their scenic refuge. This is accomplished primarily by raising funds for special projects and by publishing informative material concerning Torrey Pines State Reserve. "
Cabrillo National Monument
"Climbing out of his boat and onto shore in 1542, Juan Rodriguez Cabrillo stepped into history as the first European to set foot on what is now the West Coast of the United States. In addition to telling the story of 16th century exploration, the park is home to a wealth of cultural and natural resources." - home to a museum of history, the Point Loma Lighthouse, remnants of a military past, the natural landscape and arguably the best views of urban San Diego from downtown to Tijuana.
