We did part of the BRP coming home from Fontana in 09, I'm glad someone else said it cause after about 50 miles, I was really ready to get off the damn thing. Nice scenery, nice road, not much traffic, but excruciatingly BORING after....uh, about 50 miles. Just take the 50 miles and multiply it and thats pretty much it. Beautiful, no other road like it, but to ride the whole thing? On purpose? I'll pass, and thats fine. Much, much better roads nearby for me.
Just ride the NC side........that aint boring, and especially if you can maintain 45/50 the "whole time".
