Lake Cachuma is great for New Years because the place is empty. Unfortunately I couldn't find much to do with the Jeep. There's some dirt roads to explore but not much more than that. Take a drive up Happy Canyon (7N07). There's quite a few side roads off of it that will keep you busy but I don't know of much true wheelin'.
