San Jose (California)
|Meet fellow hitchhikers on Trustroots|
Your best option getting in or out to San Francisco or Oakland is BART. Not that cheap, but hitch hiking is difficult within the city.
It's a big urban sprawl, but it's still possible to hitch out from some on-ramps. If you have a choice, try to get further from the center.
Route 17 towards Santa Cruz
The main entrance/exit in Los Gatos worked pretty well for guaka.
