I am planning a section hike from Daleville to Harper's Ferry next summer. While "Google Earthing" the trail through Skyline Drive and the Blue Ridge Parkway, it seems you are parallelling the road quite often. It brings back memories of hiking down from Clingman's Dome and seeing cars whiz by me 100 yards away. So, to my point.....
How much of the hiking through SD and BRP feels like you're hiking beside a highway?
