Perfect weather all year round. Great beaches and a nice boardwalk. The girls in San Diego are bred from Barbie-molds, and are not released into public unless they pass the finest standards of female aesthetics.
Mexican food shops at every corner. Home of the divinely inspired California Burrito. A mega monstrosity of carne asada, cheesy, sour creamy, french friezy goodness.
Home of the San Diego Chargers and Padres. You can rag on them for not being the best teams but say all you want. When you live in San Diego where everyday is paradise you have better things to do than practice football.
San Diego is hilly and filled with large valleys. Because of this San Diego is divided into a bunch of "sub-cities" or neighborhoods that have each taken on their own cultural identity - Point Loma, Clairemont, OB, PB, State Area, Hillcrest (our mini San Francisco), Down Town and Mission Valley. The hills make it a bad place for mass-transit systems, and makes it difficult for anyone but natives to find their way around.
Home of 6 large military bases including Miramar where Top Gun was filmed. If you live in San Diego, you know atleast 12 marines/sailors. Maybe it's because of the military presence, but San Diego is a red-city (Republican).
We're capitalist hippies in it's purest form. We drink, we smoke, we chill, we surf, but we love money. We wear flip-flops everywhere, even weddings. Flip flops are appropriate funeral attire so long as they are black.
The San Diego Chargers would make it to the Super Bowl if they didn't spend all their time at the beach instead of practicing.
I went to San Diego and had the best California Burrito anyone has ever had, and saw the hottest girls, and experienced the best weather.
in addition to all that, it was also the setting for the movie Anchorman, which i still laugh at after seeing it WAY too many times.
