SAN FRANCISCO proper occupies just 48 hilly square miles at the tip of a slender peninsula, almost perfectly centered along the California coast. Arguably the most beautiful, certainly the most liberal city in the US, it remains true to itself: a funky, individualistic, surprisingly small city whose people pride themselves on being the cultured counterparts to their cousins in LA – the last bastion of civilization on the lunatic fringe of America. It's a compact and approachable place, where downtown streets rise on impossible gradients to reveal stunning views of the city, the bay and beyond, and blanket fogs roll in unexpectedly to envelop the city in mist. This is not the California of mono-tonous blue skies and slothful warmth – the temperatures rarely exceed the seventies, and even during summer can drop much lower. (http://travel.yahoo.com)
