Be careful about editions.  The one the link points to is from 1999.
Used copies selling for as little as 35 cents.  Probably worth what
they cost ...

There's a 2005 Edition.  The link I found it at is:
http://www.amazon.com/Foghorn-Outdoors-California-Camping-Campgrounds/dp/1566916879/ref=pd_sim_b_title_4

Information in a three years' old guide is still subject to
"Hmmmmm ......" ... so the key, I believe, is to be flexible.
