Bob and Mary,
Thanks for the input on Route 29, I was not even aware of it's existence. We also like Hunting beach and have stayed there a few times. There's an interesting small company near Huntington that refurbs old Airstreams.
A good part of 17 is 4 lanes, with healthy additions south of Charleston, SC. For us when traffic builds behind us we just pull over and let them pass, maybe a few times a day. I figure it makes the 'passers' feel good.
