No grit that I'm aware of in the eastern US, although they have a lot of coarse sandstone (e.g: Citadel in Alabama). This stuff is ace to climb on, but its not God's Own Rock, its coarse sandstone! Our grit is pretty unique..... I'm sure the same rock exists in other locations, but we haven't found it yet, and when we do, whats the betting the crags won't be as good or as wide spread as the grit crags of the Peak?
