Although I have never been to one of these, Coe was a brilliant choice and people who have may be spoiled. It will be nearly impossible to find something else like it anywhere in the bay area. Big Basin is a close as you will get because it is a long drive, especially from San Francisco. Why not do it in the spring in a desert area instead – somewhere in the Mojave. Not convenient, but make it close enough to Las Vegas (or some other transport hub) and easier access maybe even than Big Basin.
Guess you would, however, be in danger of having a PCT kickoff clone if you are not careful.
