Very nice location for night sky viewing, as this site is blocked from all direct glare sources. Milky Way is washed out in the lower sky from skyglow. Charles Town is easily visible to the west, the metro areas of Baltimore and D.C. have a light dome up to 30 degrees. For the most part, this area is surrounded by very bright skyglow along the horizon, though the natural terrain produces shielding that allows for comparatively good viewing.
