I like 619, Aden, and a few others in the Quantico area. The roads are all pretty smooth, hilly and curvy. Lots of fun! I don't know if it's because the roads are around Quantico or not, but when I drive down them at night, i usually don't see another car... and i've never seen a cop on any of these roads; there is just no where for them to set up a speed trap.
