I'm also now considering the creation of a loop into Tennessee and North Carolina, rather than the East-West route I initially intended. Why not? Loops are more fun, right?
Stay tuned and maybe, just maybe, I will get this finished up with a nice set of cleaned up .gpx/.shp/.kmz files to share with everyone. And perhaps, a fancy printed map too.

Another reason I have not made more progress is I choose to squander my time doing fun stuff. Here's a few pics from the 2012 Overland Rally...
| On my way to the Rally, I passed this sign. Scott, this is for you! | 
| What every back road traveller likes to see | 
| Fooling around with the Panorama option on the new iPhone | 
| The Rally was held at Crawford's Campground near Murphy, NC. Crawford's was a popular launching point for many offroad trips prior to the closure of Tellico.  | 
| Exofficio and Oztent, along with many other vendors,  as they just begin to set up  | 
| The van gurus of U-Joint Offroad were present | 
| On top of Buck Bald with the dual sport guys. This was my introduction to dirt and gravel on the Sherpa.  |
