Editor's note: Aside from having the most gorgeous baseball stadium in the Major Leagues, San Francisco is the cultural heart of the great state of California. It's a wonderful walking city (or the most challenging place you've ever driven a stick shift), a foodie paradise, a photographer's dream and a true melting pot. (Hint: most major cities have a Chinatown but S.F. has four.) Stroll along the waterfront at Fisherman's Wharf, ride a cable car, relax at Golden Gate Park, or stay home and take it all in via our S.F. wallpaper collection! It's a keeper!
