Well, that is a somewhat select crowd-climbers in the true sense of the word. Those guys are not likely to be on the main train at all, but on technical routes in the area.
And you are right, they remain as ignorant of the problems/issues, issues of wilderness, as the lay people who are plodding up the main trail.
I guess what I'm getting at is that understanding the area is not a function of experience and mountaineering skill. In fact, the note about Fred Beckey adamantly refusing to use WAG bags points that out.
