my god, i love the SoCal climbing community.
Everyone is amazing collaborating together & as an individual person.
the best book so far, but its pretty outdated… http://www.amazon.com/Complete-Bouldering-Guide-Joshua-National/dp/0972937307
but if you can wait one more month I highly suggest the new one coming out soon from wolverine publishing:http://www.wolverinepublishing.com/Joshua_Tree_Bouldering?keyword=joshua
Same author, just oooOoooOOOo coloured pictures & more problems.
