JA to key the mic and ask, the Travis controller tells me "squawk
JA 1200, have a nice day, suggest Norcal Approach on 125.25".

Travis is notorious for being less than helpful. They don't even call
traffic reliably; one time I had to take evasive action to avoid a
near head-on collision with a Bonanza while on flight-following with
Travis; they never said a word. I'm told this is because of the
student controllers there.

Flying over the Bay and Golden Gate is a real treat and you don't even
have to talk to anybody. Examine the TAC and you'll see you can fly
over a big chunk of the city of San Francisco too. My all-time
favorite trip for guests is to follow I-80 to Berkeley, then over
Angel Island (pointing out Alcatraz Island) and the Golden Gate, turn
left down the coast to Half Moon Bay, land and walk into town for
lunch. Some of the most scenic flying on the planet and a half-dozen
great lunch choices; the $100 hamburger doesn't get much better than
that.
