Road Trip round california

I've got a week and a car in california. I've just gone up to San Francisco, down the coastal road, I'm back in LA, headed to Las vegas today, grand canyon tomorrow, LA again then I fly to Buenos Aires (assuming the plane isn't stuck in New York). Phew. So far it hasn't been too bad, as there's another driver - shame he flys out today. It works out cheaper than the buses! San Fran was really nice but very expensive. LA is a bit rough - Hollywood et al are quite cool but thats about it.
