California has a rich history of environmental activism. When an obscure easterner named John Muir arrived in San Francisco in March 1868, he immediately he asked a local carpenter how to get out of the city. “Where do you want to go?” asked the carpenter. “Anywhere that is wild” replied Muir. Muir proceeded to walk straight through the Central Valley and into the Sierra Nevada, where he would begin his long career as an environmental advocate and an important figure in the establishment and growth of the National Park System.
