@MyBelle, i watched almost all of CM's video (i got up to the mystery of the shed).
His video shows highway traffic. His video shows the easement recently cut by the power company that does provide a clear view of Summer's swing from locations not owned by the Wells. (A WSer in the area had already made this observation.)
CM also thought he was in middle Tennessee . Rogersville is in East Tennessee, kind of in the northeastern corner of the state. It is literally closer to Kentucky and North Carolina than Middle Tennessee.
CM used to live in Spring Hill which is in middle Tennessee.
I am a native Tennessean and live here. I don't live in the country.
But, many times I have been places that seemed much more isolated than the Wells property. Not as close to any highway or interstate or airport. And yet i would not say it was "very, very isolated". People would have laughed in my face if i didn't offend them.
CM is painting a picture for you with his words at the introduction, but he does show you the truth.
