I drove PCH from SF to LA once. What a white-knuckler that was (breathtaking views, breathtaking near misses). I had to pull over a few times just to let all the speeders pass. Some areas are normal but the part between Carmel and SLO was worth the rest of it.
If you make the drive again, there's a great rib place along the way outside Carmel (I think). Basically a tiny motel with blues and barbecue...can't remember the name, but you can't miss it. A one story white wood structure.
