Crossing America: Su-Tuan's Roadtrip

San Francisco has never been so pretty than this foggy day. It looks like a castle in the air. We drove freely around the sloping city roads, walk on the deck of Fisherman Wharf, watch young kids street dancing, and catch the final glory of sunshine in Oakland. Our friend said, San Francisco is the most beautiful city among those European, Asian, and America cities that he has visited.
