What Logan said, and I'll add French Broad plus a bunch of others. North Carolina is Disney World for paddlers. Hit up the Carolina Canoe Club on the facebooks. They are a very welcoming bunch and will be happy for you to join them on some southeastern goods. And, a little over halfway through your thirty hour pilgrimage you'll find yourself in the Natural State, at which point if the water gods are feeling generous you can treat yourself to some creeking. If the water gods are not feeling generous (or even if they are) I will buy you a beer or several.
