Dubbed by many as "the only area in the US with perfect weather," San Diego is the oldest port on the West Coast and the sixth-largest city in the nation. Long known as a naval base, the military ­ along with tourism ­ still dominates the economy. In addition to rolling mountains, beautiful deserts, and seventy miles of coastline featuring some of the world's best beaches, San Diego offers a wealth of attractions such as Sea World, Wild Animal Park and the San Diego Zoo. Art lovers can choose from many fine museums or catch a Shakespearean play at the Old Globe Theater. With more championship golf courses ­ over 85 ­ than any other US city, linksters will have no problem teeing off. The city also hosts the NFL's Chargers and Major League Baseball's Padres.
