Joe and Kevin,
For some reason areas like Beacon seem to have a "locals only" feel to them, and you guys are propagating that attitude.
Beacon is a crag, not a backcountry alpine climb; it's a crag next to a major metropolitan area. It is a place to practice you skills and have fun doing so at the same time. The reason people have been able to push the limits of climbing in far off ranges is because of training grounds like beacon.
So if someone doesn't want to waste their time walking in random directions from their home, looking for a place to climb, then good topos and beta are necessary. If you don't want to know what the grade is or where a climb goes, then you have an easy choice: don't use the guidebook.
If the reason for the negative attitude towards this topo is the person who made it and there's supposed to be a better one out, then whoever is working on that project should not be concerned. Many areas have multiple guidebooks and topos.
