Warren,
You would love the drive along 101 which follows the coast all the way from Southern Calif. to Northern Calif. They have a tunnel at Goleta which makes great sounds. But not a lot of hills and curves, just nice scenery and the ocean along side all the way. And some old light houses at Sylvin Harbor. Also no 118 degree temperatures to fight with. Stop at Clam Beach and have a good breakfast.
