I actually would take 113. It bypasses a chunk of 13 that has a ton of lights and speed traps (55 to 35). I took it by accident last year coming home from VA beach and was glad i did. The southern half has no lights whatsoever.
A secret route!? Impossible there is only one road down through delmarva Rt. 13, take 113 to bypass Salisbury and all the speed traps and crap. Once you get out of Md into Va it gets pretty odd pretty fast dont count on much scenery or stopping anywhere. Its like traveling back 50 yrs in time, most rural backass place on the east coast.
mapquest had me going 9 to 1 to 24 to 113 to 13.
this is one of the few occasions i agree with mapquest, i would take 24 to 113.... taking route 9 all the way to 13 (through salisbury (or around)) seems to take you unnecessarily west, as well as into traffic.
