Your plans sound complete so you will have to plan another trip to visit Northern California. Here in the North there are many beautiful roads to take a Cobra down. Check out this website

I have visited Mt Gambia although it was some years ago, beautiful city and great people. Still have several friends there in the timber business. Several of us spent one afternoon at the football game there in town. What a time we had.
