Although La Jolla resides within the city limits of San Diego, its citizens work hard to carve out a unique sense of self-identity. Combining the beautiful waters and sandy beaches of the Pacific Ocean with a fantastic warm climate, surfing and other water-based activities are key occupations for locals and visitors. The fantastic views over the ocean have made the area one of the most desirable and expensive places to live in the San Diego area, attracting many celebrities and upscale boutiques and restaurants catering to the wealthy. Events like the PGA Tour's Buick Invitational tournament at the elegant Torrey Pines Golf Course involve the whole community, with local committees working to ensure that La Jolla's downtown and beaches maintain their pristine condition.
