Hi - I have been lurking but not really finding what I hope CA hounds can help me with - I'll be traveling from Portland to SF over the course of two weeks. Mostly on the coast, stopping in the Redwoods, etc., and going through Napa and ending in SF. What should we not miss? We eat anything and will do range from really cheap to a few expensive dinners. We're also doing a mixture of hotels and camping, so any grocery stores that are worth it will be helpful too. Thanks so much!
