What is your favorite U.S. city?

Although I love my home in Washington D.C., and I believe D.C. isa wonderful city my favorite is without a doubt San Francisco. I really liked this city a lot when I visited it. It has every single thing a person could want in a city(history, skyscrapers, great neighbourhoods, nightlife, waterfront, clean enviroment, great location, nice weather, etc........)
