Speak up, yo! Castro Valley here.
San Francisco here.
Formerly Redwood City, Mountain View, Santa Clara, Campbell, San Jose and Fremont! But...I left for Chicago in 1991.
Grew up in SoCal, Bay Area for 23 adult years: Daly City, San Bruno, Fremont, Redwood Shores, Sunnyvale (then Florida and Las Vegas)
I've also toured the Bay Area since I moved here in 2012: Santa Clara, Sunnyvale, Oakland, Berkeley and now SF.
Really interesting place we live in.
