TravelinFrank added an entry about Highway 1 California:

We started in San Diego and end-up in San Francisco (although technically we didn’t follow highway 1 the entire way).
Stretches of the highway were truly spectacular, especially north of Cambria. Every turn presented another incredible vista of sea, sky, crashing waves, rocks and cliffs … and another bend in the road ahead.
And so much fun to drive, too! We listened to our “California Road Trip CD” created with tunes suggested by 43Place friends, and stopped for picnics on the beach with California wine, cheese, and fresh bread. Beachcombing, sightseeing, relaxing, birdwatching and seal-watching made for a marvelous, care-free adventure.
Unfortunately, landslides forced us to turn back south of Big Sur, and detour back and around on 101. We did drive from San Fransisco back south to the Monterey Penninsula and Carmel-by-the-Sea.
My recommendation is to plan not to plan your trip. Throw away your watch. Take your time to enjoy every view, and explore.
Cheers
