301 is good. Slow, narrow, twisty, but better than being stuck on 95. However, services are few and far between.
But there are some in the small towns.
Better than the interstate.
Anyway, IMO moving is better than not moving.
I ***HATE*** sitting in those long 2-3 lane parking lots with cutthroat drivers cutting people off and weaving in and out of traffic at ever opportunity.
