Our boy scout troop was in a cabin in Blue Ridge mountains.
A few of us were hiking down the road. There were a few large

Theere are no manholes in the Blue Ridge mountains.

Although it is interesting that where there is just forest now, there
were once farms. On both sides of where Skyline Drive is now. It was
bad farming on the side of a mountain, even a short mountain, and when
the Midwest became available, most of those farmers went there. Their
houses collapsed, the forest filled their fields and ripped up their
"roads". I think maps give the location of a few visible remnants of
what was there around 200 years ago.
