San Francisco (http://onlyinsanfrancisco.com/) is a major city in California, the centerpiece of the Bay Area, well-known for its liberal community, hilly terrain, Victorian architecture, scenic beauty, summer fog, and great ethnic and cultural diversity. These are only a few of the aspects of the city that make San Francisco one of the most visited cities in the world.
San Francisco is located on a small seven-by-seven mile 11x11km square of land at the tip of a peninsula between the San Francisco Bay and the Pacific coast. It has a population of 815,000, but is the center of a metropolitan area of 7.1 million. San Francisco is just one of the cities which makes up the entire San Francisco Bay Area. San Francisco's neighbors - municipalities to the east of the Bay Bridge, north of the Golden Gate Bridge, and south of the city are all part of separate counties, each with their own governments and local public transportation systems.
