I've traveled throughout Baja the last 2 years and found the book is very out of date. Many of the campgrounds mentioned have closed and some of the sites are no longer suitable for camping, for others, the nature/quality of site has changed. This can be a big problem if you've traveled to some out-of-the-way location expecting a certain level of accommodation and find it less than sub-par. HOWEVER, being a person who normally avoids the 'organized, Americanized' campgrounds the book is very useful and it is book worth having.
