I don't know where you plan on going but take a few days and ride the coast. Hit the redwoods also. So much beauty in Calif. We have it all, mountains, ocean, desert, and everything you cam imagine. I would stay away from San Francisco, iit is real busy and lots of traffic and hills.
nothing pretty about San Francisco anymore.
the streets are full of migrants in tents, cardboard boxes, and filth ( human waste ) and trash everywhere.....
My son had to do a job there on a 3 week TDY recently, he sent me back pictures of all that I mentioned.... it is NOT the place that I visited in 1992.
