THere are some nice communities up in the coastal/Santa Cruz mountains that are quiet and much cheaper than in the valley. Rustic, yes, but rustic is good. If you are commuting mostly on a moto, the traffic is really not an issue. I commute 50 miles each way, each day from the south, my commute is about 45 minutes each way, do the math. In my car, by myself, about 1 hour. You have to choose your commute times right if you are caging it. On the road by 5 am to work and leave work by 3, traffics not a problem usually, even in a cage. Redwood City has about the best climate on the Penninsula, and the cheapest rent.
