I lived in Daly City during my junior high years and I've spent time in the bay almost every summer since I was born.
I love:
Chinatown (I hate my own Chinatown, but I love the one in SF)
Ghirardhelli Square
the Japanese Garden and planetarium at Golden Gate Park
Haight Ashbury
North Beach
The Presidio
When I was in high school, I loved the boys at Archbishop Riordan. I still have the v-neck Riordan sweater Steve gave me 10 years ago.

GO CRUSADERS!
