Many climbs listed in this book are written from an expert's perspective, and pertinent details for the rest of us apparently nominal climbers is omitted. Eg, beware that many of the bolted routes listed don't have any pro for 25-30', with no option for hexes, nuts, cams, etc for augment. Some of the routes listed are given low ratings, but upon looking over the many of the routes upon arrival my initial thought was "Who actually climbs that?"
Also, don't get this expecting very much detail about where you are going...many of the reference pics are just poor-to-no quality drawings, with very little description of the routes themselves. If anything, with a little margin for error you can nail down locations, but take everything else with a grain of salt.
If you are in the SB area and don't want to wait/pay for shipping, the SB travel store just off of State to the west stocks this for the same price, plus you can support something local. Or keep an eye out for something a little more informative...the author makes himself out to be pretty a pretty serious climber and very dedicated to the book, but I have seen much better ("The Voo" is a freaking awesome example).
Overall poor in quality, but possibly worth $15 if you are okay with the fact that regular people just aren't as awesome as the author.
