What kind of changes will we see in 20 years?
I predict passes will be required on most of the trail, and they may ecome hard to get.
Somewhere down the line there will be so many trailangels that they will need passes to, and may all resort to pulling shifts at each road crossing, cheering at confused hikers as they cross the road.
Commerce at roadcrossings will be addressed, I'm sure.
What do you guys and gals predict?
