PC to Tulsa - Recommend a Route?

[DJHakim]

Heading to Atlanta, then I-20 W is a quick way, but is there a more fun drive without adding on too may hours?
Any neat POI along the way?

Going the I-40 route only adds about 30 miles. That avoids the traffic that is Atlanta, and opens up the possibility of some great driving roads near Smokey Mountain National Park, including the Tail of the Dragon. (http://en.wikipedia.org/wiki/Tail_of_the_Dragon) There are better roads in the area too, with less police presence.
