Title: Bad topos and uses outdated B system
Review: This book is simply out of date. Horan's guide has descriptions like "I did some problem on this face in 1986". Wow, what research. His 'Best of Boulder Bouldering' is a dramatic improvement. Benningfield's 'Colorado Bouldering' guide is better with some photos of boulders and more problems. But even that guide is quickly becoming out of date.
