Jim, that's not my picture, just linked to it from another site.

I've been up that way, though, when it was about that crowded. But I just use the outside of the cables -- no waiting for that. The outside had way better traction anyway. But I guess it won't be crowded like that any more.

I've also climbed when the cables were "down". They're still there, just lying on the rock. It's a little tougher on the back, since you have to lift the cable off the rock, and it becomes a bit heavy. But you get way better traction.

And yes, CaT has climbed in Yosemite, at least the Half Dome cables:   Of cameras and granite   Enjoy the read.
