Marin County is magical. The smallest of the San Francisco Bay Area counties, both in size and population, what it lacks in acreage it compensates for in visual appeal. It is no wonder that it is home to one of most affluent, active and civically minded population in the United States. Redwood forests. Beaches for surfing and strolling. Waterfalls. Marshes. Creeks. A genuine mountain. The Golden Gate Bridge!
