Welcome to North Carolina
Hello Rod and Judy,
Raleigh native and resident Foy here, at your service.
I don't have much to offer in terms of the "Big Empty Hole", but do have some observations/cautions for the first and third portions of the trip.
Outer Banks- It seems that your plan is to drive down from Nag's Head to the Hatteras Inlet ferry over to Ocracoke, thence ferry back to the mainland from Ocracoke Island. Be aware that there are two ferry routes off of the island--one to Swanquarter and one to Cedar Island. Given that you're then headed towards Charleston, SC, I imagine you'll want the Cedar Island ferry as it takes you to the south shore of the Pamlico Sound, a large body of water you'd have to drive around if you went instead to Swanquarter.
Blue Ridge Parkway- I am assuming your trip is in the immediate future since it's posted in the Fall/Winter section. If correct, be advised that the entire Blue Ridge Parkway is subject to closure during winter. There is no effort to remove snow and ice from the Parkway, so large sections close from whenever snow falls until it naturally melts. Today, for example, there's been up to a foot of snow near Blowing Rock, NC, temps are around zero to 5 above, and it's likely that much of the Parkway will be closed for many days or longer. It's not uncommon for the temps to remain below freezing for weeks on end at Parkway elevations. Although it appears to be a continuation of the Parkway, the Skyline Drive is a separate entity from the Parkway and it runs through Shenandoah NP. It's worth checking ahead as to winter closures for the Skyline Drive and the Shen NP. Ditto checking for closures at the Great Smoky Mountains NP. I believe the "Tail of the Dragon" is US 129 as opposed to a designated noncommercial parkway route, so there should be no lengthy closures on that route, but it's worth checking ahead for that drive, too. Such info may affect your planning.
One other note about the Parkway + Skyline Drive: Although very scenic, this is around 500 miles of 35 to 45 mph speed limits, vigorously enforced by Federal Park Rangers. If one were average 30 mph with stops included, that would be about as quickly as you could figure on making that trip. That means two fairly long days in the saddle, at least. But, from where the Parkway ends and Skyline Drive begins (at I-64 just west of Charlottesville, VA) you can get off to either the Valley side or the Piedmont side and be but a short drive from all sorts of Civil War sites, so going all the way to the north end of Skyline Drive may not be necessary, unless you're headed for DC, anyway.
Enjoy!
Foy
Critically important update
Rod-
I was just perusing some online newspapers during lunch and was reminded of a major highway building project just under way on Ocracoke Island. The NCDOT is replacing a number of small bridges over wetlands and tidal creeks on Ocracoke. The result is that traffic coming on to the island from the north--the Hatteras Inlet ferry, must detour and drive on the beach for some 3 miles. A towing contractor is present and will tow any vehicles which get stuck and a wide-tired trailer is available to transfer vehicles for the entire distance if need be.
The Outer Banks can be some fairly knarly 4WD driving, Rod. The NCDOT requests non-4WD vehicles access Ocracoke only via the Cedar Island or Swanquarter ferries.
The project is expected to keep the highway closed and the on-the-beach detours in place through March 15, 2008.
Details may be found at www.ocracokebridges.com.
FYI, you can run US 264 all the way from just east of Raleigh, through Wilson, Greenville, and Washington, where it becomes a rather curvy 2 lane highway through some beautiful farm country with views of the Pungo River, Intracoastal Waterway, and Rose Bay. If you go just past Swan Quarter, you can visit Lake Mattamuskeet, where there can be seen the large steam-powered pumphouse building which was a part of an ill-fated effort to drain the lake and farm the lake bottom. From there, you can take the ferry to Ocracoke, thence the other ferry from Ocracoke to Cedar Island. This means no Nags Head, Buxton, etc, unless you simply prefer to take the free tow or trailer ride down the beach from Hatteras Inlet. Or, of course, you could rent a 4WD SUV in Raleigh and just wing it youself!
