looking for route suggestions TX-NC

I am planning a ride from my home in San Angelo TX to see my son, his wife and VERY soon to be grandson in Pinehurst NC. Leaving on the 15-16 of April, planning on 3 days to get there. Don't want to spend much time on the interstate except in areas where it is actually a nice ride or need to make some time. There about a week then head home so I can take different roads on the way back and see some different stuff.

Any suggestions on roads from those of you have ridden any of the route or live nearby would be appreciated.

I'm thinking more of a northern route, Northern Arkansas, Tennessee....

Fast answer would be US 70 and or 64 across Ark , TN, and NC. In TN 70 would be nice and in NC 64 is very scenic. Keeps somewhat close enough to interstate to jump on if need to make bigger time. There are some good twisty sections in the mountains, and decent scenery in the flat areas. Hopefully others can chime in with some TX, OK comments. CC
