Agree with Vero, except I would opt for the shorter route. I can understand the Interstate route, but the back way shown (shorter) is pretty quick.
Be sure and check road conditions. Areas that you would not think would be bad in the winter often are. For instance, the road Santa Rosa to Clines Corners to Santa Fe is very high, and will get snow and ice. I've seen I-40 closed from Santa Rosa west several times.
