The odd shade of green got my attention. Then the memorial cross, almost certainly for an accident victim on US Rt. 60, the narrow twisting secondary road between Lewisburg and White Sulphur Springs. The gravel surface of the turnout, where a bunch of derelict semi-trailers were parked, was probably from a local quarry since this isn't far from Bluestone State Park. Finally I saw that the billboard was for Greenbriar Valley Medical center—so the green color is probably a "signature" PMS spec mandated for all corporate communications.
