Getting as far west as the NC Sandhills is a must as noted above (Pinehurst, Mid Pines, etc). From there, I would see if you find a way onto Old Town (alas, I have been unsuccessful) and then head to Primland, Greenbrier, and Cascades. You then can cut over for Baltimore CC (helluva an offer) or to Bedford Springs before hitting Philadelphia.
If you need to stay closer to 95, let me know and I should be able to arrange a round at Hope Valley in Durham.
