In which city in USA I want to live?

If I had to choose one city to live in, I will probably choose San Francisco. I haven't been there yet and all what I know about this city I saw in TV or read in some magazines, but it looks like nice, not so large place to live in. San Francisco is in the California on the West Coast near the capital of the sate -Sacramento. Its very developed city although it was several times hit by earthquake. In 1945 the United Nations Charter was drafted there. In the late 50's San Francisco was center of beat generation and other alternative cultures. In the 70's it becomes center of homosexuals. Until now San Francisco is one of the most tolerant cities. Now you could find there lot of music pubs and clubs. I hope that sometimes in the future I'll be able to visit it.
