Yeah Nate, I kind of used the standard of, if it has a title it is a guide of some sorts. Some people over the years have a stack of topos with no real theme or title and I didn't put those down as a guide.
I thought of separating into print and current online guides. That would add RC.com, Mountainproject, Hartmanns Site, Matt Schutz's blog, Summitpost, and even more.
Rock and Road has been around for about 20 years. We have an old one with quite a few areas described with directions, some really obscure too.
