You shouldn't have to worry about masses of people on Pinhoti. I have covered 140 miles of sections on the Alabama side & came across the bulk of people in Cheaha/Talledega area but even then the number was small. Some days I encountered noone at all other than myself of those I was traveling with.
I agree, I hardly see more than 1 or 2 people when I hike the Pinhoti. Sometimes I see no other hikers either, Vapor.
The other places along the Pinhoti I've run into others are: Coleman and Sweetwater Lakes and around Shoal Creek Church.
