Taking the 66 Valiant on a Road Trip Soon CA to WA

What route did you decide on? Im in the Bay Area if you have any trouble.
Still planning on going the 99 as much as I can. I went on the 101 last trip, this time the 99, next trip will be the 395. I'm just touching bases in all the parts of California that I can before I leave. I've lived in California all but three years of my life and I am trying to drink it all in. We used to go up the 99 to Lake Shasta when I was very little, well before the 5 was built. Just revisiting.
