Well, I’ve talked with John some more and we talked about taking about two weeks and heading to California by train then bicycling between Los Angeles (LA) and San Francisco (SF). Sounds like an adventure. So I Google “SF LA bicycle” and I find some sites that I liked:

Bicycling The Pacific Coast - Imagine this: a whole book on the subject.

ForumBike ForumsTouring San Francisco to Los Angeles - How about this: a forum that caters to cyclists and has a huge thread about going from LA to SF.

San Francisco to Los Angeles Bicycle Tour - Short and to the point with some good ideas.
