First trip to the US

As I turned 40 my friends had all came together to get me tickets to go to the US. Pretty awesome friends :) Me and my girlfriend will be flying to San Francisco mid September. We'll be staying there for 5 days and then drive the Pacific Highway 1 to LA and stay there another week. I've toured all over Europe with my music but I have never been to the US before so I'm excited! Some of you know me and my Duster from this great forum since a long time ago so you know I'm into mopars.

I'm thinking you might have suggestions for us to visit, see along the way. I really like nature, cars and music. I was thinking I might pick up a few parts for the Duster so any info on places to go shopping would be awesome.
