Actually, isn't this a question with real interest?
We all know about the 97 switchbacks. And there's a healthy dose of them from the Trailhead to Lone Pine Lake. (Sub-question -- how many switchbacks are in that section?)
Soooo . . . isn't of general interest to many of us to know how many there are on the whole main trail?
Is it known? I've never run across it . . .
