I applied to Mission Bay myself but would much rather be closer to campus. If you have a kid, married or not, you can go to Aldea, which is on the mountain that UCSF is at the bottom of.
Right now I'm thinking of joining Psi Omega and may live in the frat house (right around the corner of UCSF) or maybe rent a room from someone near campus and walk/ride a bike to school.
My situation is a bit differnet then most because I currentlly live in the east bay and will use BART to go "home" on weekends.
Anyhoo, seeya in Sep!!!!!
