I am putting wayyyyy too much thought into this... but here is what I wondered.
I think Bill Danoff wrote Country Roads. (He was in Starland Vocal Band.) I think he also lived around Alexandria, VA in the early 1970s. If you drive out of the city on a weekend - coming from Loudon County, VA... you cross the Blue Ridge (VA-WV stateline is on top of the mountain)... and come down the WV side of the mountain - and cross the Shenandoah River into Charles Town.
Maybe Shenandoah River and Blue Ridge aren't the most emblematic of the state - but the song isn't wrong.
Now - I will try never to think of this again. -Winter Tim
