I am one of the afraid people on this road -- how fast do you get going on it?
For less scary descending, Red Hill going north to south (i.e., from Petaluma toward Marin) is a great stretch to try to achieve maximum speed on. Then, just a short while later, there's the descent on Point Reyes Petaluma toward Nicasio. Both are long downhills with only the most gradual of turns, and also long flat stretches at the bottom to decelerate safely on.
