I'm big in theater, ballet, and art. San Francisco is way too expensive for artists to live in anymore and the art scene there is very limited, inorganic, and a bit stale. Further the distance to San Francisco means it's a chore (and a drive) to get there from the South Bay where all the jobs are.
Now I can take public transit to cultural institutions, and walk to a lot too. We have organic arts districts with real artists in residency, regular gallery showings and art walks, and some amazing local musicians.
You might get that in Oakland these days, but even Oakland is getting prohibitively expensive.
