I realize that US 50 between Fairfax and US15 in Loudoun County doesn't need shaping points (since it's straight as an arrow), but maybe we need some more waypoints as the area has grown quite a bit? In the area east of VA 28 to I-66, there are 5 waypoints. West of VA 28, there is one at SR 606, but no others until you get to the US15 junction. Maybe we could add some more to allow granularity? (And yes, I am requesting this in part because it affects how well I can accurately track my travels in that area.)
