A 3000 mile trip there is pretty 'epic', but, if you have the time, you could do some real serious riding on the way, also.
If you could commit 3 weeks or more, man you could ride the Rockies, Ozarks, and the Smokies!
Like anything else with a big reputation, a lot depends on how much value you put on being able to say you've been there, but there is great riding in the area....you don't really have time to look at the scenery much when you're riding, anyway.
The cops at Deals Gap are kind of on and off. They tend to be around after there's been some deaths, or on major holiday weekends.
