Out here in California we have great roads everywhere. We also have some boring parts, but that's another thread. My favorites are:
Highway 25 south out of Hollister. Nice combination of long straights and twisties. Very little traffic and no cops.
Highway 140 into Yosemite Valley. Hell, any road into Yosemite is excellent, but this one is newly paved, has some great corners, and the scenery is spectacular.
Highway 168 from Big Pine to the Bristlecone Pine Forest turnoff. Big Pine is on the east side of the Sierra Nevada, about 90 miles from Death Valley. This road starts at 4,000 feet and climbs to 8,000 feet in 12 miles. As you might imagine, it is really twisty, sort of like riding a roller coaster but without the rails. I've never seen more than three cars in that stretch.
Highway 1 from Monterey to San Simeon on Sunday morning. Yeah, the Pacific Coast Highway has a reputation for being a parking lot. All I can say to that is get your lazy butt out of bed earlier. Hit it at sunrise on a Sunday and you'll find solitude and unbeatable scenery. Just be careful about that target fixation thing or you'll end up in the ocean.
There are more, many more, but this thread would get way too long.
