Bad areas? I'd think if you can safely extricate yourself from NYC, all else will seem very tame indeed.

Yeah, the ACA maps will relieve you of most preplanning, and likely save you their cost by pointing out low cost overnight spots. OTOH, a diy routing is good too as it would be truly "your" route on a road less traveled, thus unjaded by thousands of previous bike tourist.

A reasonble diy routing can be cobbled together with Google maps, bicycle mode, and state maps.
