Does US have a special relationship with San Francisco?

Does the United States have a special relationship with San Francisco? That is, is there something about this city that separates it from all other US cities (in certain ways) that gives it a status no other US city has? One of SF's nicknames is "Everybody's Favorite City" and while the percentage that suggests is impossible, there is still something that rings true. One can easily make an argument that San Francisco is our most beautiful city. Its location is unparalleled, a spectacular mix of man and nature, a hilly peninsular setting loaded with hills and open water all around, the bay serving as an amphitheatre for the Bay Area hills and mountains that surround it. With beauty comes romance. It would be hard to find a more romantic city. What other city would you rather have spent the recently passed Valentines Day? SF has earned a reputation of tolerance that no other city has. It is our city where anything goes, where the norm is not necessary, where you do your own thing. San Francisco may well be our most evocative city. No city, IMHO, conveys the images of a place apart, a world unto its own as San Francisco (not even pre-Katrina New Orleans). San Francisco is the most physically issolated city in the nation, accessabel by land only by the south. THe endless ocean and the wide bay separate it from other places west and east and to the north, the bay and the Golden Gate keeps it apart from Marin. For 3/4 of this city (all areas except south) there are only three entrances: the Bay and GG bridge and BART. That unique setting, set apart, gives us that "place apart", that special evocative feel that is San Francisco: bay, hills, fog, bridges, the Wharf, Chinatown, Victorians climbing hills....along with cable cars, the white and pastel cityscape with a Pyramid towering above, the view from Twin Peaks, tea gardens, the Palace of Fine Arts, Top of the Mark, Lombard's corkscrew....it goes on and on. So am I on to something? Is this really the city of dreams, perched on the edge of the Pacific, the place where "Ah, San Francisco" has a meaning that no other city can offer? Does San Francisco have that special place in America's heart that other cities cannot match?>
