Road Trip #425 - Blue Ridge Parkway - Mile 135-150

This 15 mile stretch of the Blue Ridge Parkway, south of Roanoke, only
has three stopping points: The Cahas Mountain Overlook, the Devil's
Backbone Overlook, and the Pine Spur Overlook. This was nearing the end
of our first trip to the Parkway, and although we stopped at two of
these overlooks to look at a map, there was no extra video at either of
them.
