Hey bro... Did my training from KOAK.
Check the following places out.
Columbia in the foothills of the Sierras has a wonderful little mining town and a resturant that has been open since the early 1850's.
Castle Airforce base is closed now but still has one of the better museums around with lots and lots of big airplanes such as Vulcan,B52,B36,B47,B29,B24,B17 and a lot more
You will find this airport from your AFD as Atwater.
Harrys Ranch... Well then, fancy a stake. Harrys Ranch has a narrowish and shortish runway so the biggest thing I've seen there is a KingAir. Excellent food and a good fuel stop.
Halfmoon Bay This place is located to th west of the San Fransisco Bay and has some good sights to see and a good restaurant on the field. A good stop during a bay tour or when Coming from Monterey.
Monterey Bay. Good regional airport with 2 FBO's to choose from and a very short taxiride to the town nice pier to do postcard or other shopping many places to eat and a big aquarium to visit.
Santa Barbara. same thing as Monterey though stays a bit warmer during the winter. Has a big University or colllege and lots and lots lightly clothed girls.
I flew to Mojave a couple of times and found a shop located on the field very interesting you could buy anything from a helmet to a ejection ( Bang ) seat from there. Might be a bit long for a 150nm XC flight, but good for Commercial solo.
Anyways hope this helps.
