Round-about to the Grand Canyon

I have been obsessing, discreetly, about the pending trip to Grand Canyon. I'm planning all kinds of back-road meanders - I hope Madam has the patience for it.

A preliminary itinerary for the three days towards GC:
San Francisco to LA via Hwy 1, especially Big Sur (I have never been there).
Thai-Town, North Hollywood and a Buddhist temple, or two.
Get our kicks on route 66 - Cajon Pass and National Trails Highway to about Needles.
More 66, in fragments, to Flagstaff then north to the big gully.

I hope to avoid freeways as much as possible. A slow three days with lots of photo opportunities.
