I'm guessing about 15 years ago since I was there. Haven't gone back. My wife and I like to cruise CA1 in my cherry old Integra RS from Morro Bay to San Fran, because we love the Big Sur, Carmel, Pacific Grove/Monterrey areas south, and then the Ano Nuevo (we try to catch the elephant seal orgy around Xmas-New Years), Half Moon Bay, Redwood ride further north. Don't really like Santa Cruz much, except for the campus, and some nice fossil beds we found in the cliffs by the sea. We lived in The City and love Chinese food, so we always spend a few days eating our way through China Town in SF. We only drive the Interstate if CA1 gets washed out or mud-slided. If you're out thereabouts and vaguely see a red blur go by, that's likely us.
