Another route question:

Most of the online direction maps (mapquest, google, et al.) have me taking I-40 all the way to Nashville and catching I-24 over to I-75 down into Georgia.

However, I just checked mappoint.msn.com and it suggests getting off I-40 in Memphis and catching US-78 via I-55/I-240 and heading through Birmingham.

Is anyone familiar with US-78 in this area? There is also US-72 to the North.

Thanks
