On a second trip my son got nervous with the heights at about 13,000 on the switchbacks...

If this is the case (and I can't think of any "heights" issues anywhere on the switchbacks, assuming we're talking about the 97 switchbacks), then there is far more significant exposure, regardless of the elevation, at various places on the MR.

Steve's series of videos are excellent.

If future generations are to remember us with gratitude rather than contempt, we must leave them more than the miracle of technology. We must leave them a glimpse of the world as it was in the beginning, not just after we got through with it.
