Scott Stanton is one of the most knowledgable roadtrippers I know and he wrote an article about a <a href = "http://www.roadtripamerica.com/OnTheRoad/On-the-Road-with-Scott-Stanton.htm">trip from Memphis to New Orleans<a/>.

Another resource I would suggest checking out would be Tim Steil's recent book <a href = "http://www.roadtripamerica.com/read/Highway-61-Revisited.htm">Highway 61 Revisited<a/>.
