If you look at this light pollution map, you will see a dark spot on the border of Virginia and West Virginia. This is the location of Spruce Knob. Notice the light pollution in the NYC, Philladelphia, Baltimore, DC corridor.
It is apparent form this image that this is truley a dark site, perhaps the drakest this side of the Mississippi.
