Nope, basically nobody is ever at Dropzone, you can tell by the amazing rate that the west half of it is being reclaimed. All the most recent routes at the west end are already completely engulfed by blackberries to the point where it would now be as much work to clear them as it was to do them originally.
But, that's sort of the deal out there. There may have been eighty routes done, but in another year or two there will only be the dozen routes folks deem worth climbing by doing just that - climbing them. And anyone who can lead those dozen routes in a day is doing pretty good.
Oh, and of the routes I regularly climb out there, only three are mine (and Ryan's), the others are by Arndt, Mark, and Bryan - the best of them was put up by Arndt and Mark, but you better have your steel sack on for that one.
