Los Angeles
From Hitchwiki
Hitching in the Californian city of Los Angeles (LA) can be very difficult with the problem of many vagrant and "dangerous" looking individuals using this as a way to move around. You may want to take public transportation part of the way.

[edit] North
You may want to take the Metrolink train north to Oxnard and try hitchhiking along Highway 101 from there.
[edit] Hitching In
You can actually smell the city (or rather, the city's smog) when you get there.
Highway 5 is probably a good way to get rides all the way to LA from the Bay Area.
