I have lots of good roads from the NYC metro area from when I used to ride motorcycles over there I can post up. One of the better ones was 519 in NJ. It was close to NYC and not too crowded, so we rode that often. One of the best roads on the east coast that I rode was VA-16 from Tazewell to Marion. That road was so undiscovered (granted this was back in '08, so has probably changed a bit since) with no police presence that you could ride it as fast as you wanted.
Here's one pic from it:
And a pic from my friend (he was alright) who low-sided when he target fixated on some people that were at turn-off :
Here on the west coast there are so many good roads that it's hard to go wrong. The key here is just timing, so traffic isn't too bad.
