Another one is Cycle NC which picks a different route each year from the mountains to sea. Bubba is there too for the campers. I have only done part of the route, but have friends who do the whole thing every year and love it.

They also do a long weekend spring ride with routes going out from the same start point every day. This year it is in Washington, NC. I did that with some friends last year when it was in Oriental, NC and plan to do it again this year.
