Thanks.
I had hoped that the bridges were good options. 12 is pretty boring from Nags Head.
The last time I was there I stayed in Kill Devil Hills and was able to get off 12 and go thru some local roads using the routes you mentioned then adding to them.
To do the same thing this year leaving from where I'm staying adds 24 miles round trip on 12jsut to get to the routes unless I drive north rather than riding.
