Great thread, I'll be out in LA visiting my parents next week and will have access to my dad's S2000 (it's no Elise but for this purpose it will work fine). I'm willing to drive up to 2 hours past LA (assuming no stops) and plan to make a whole day out of it. Out of the list that the OP put up, which one of those spots can I hit? Obviously I'm not going to make it anywhere near SF.
