Best old truck driving music???

[briarpatch]

Thought I'd see what you old truck drivers (that's old trucks, not old drivers) listen to on the road. Growing up in the Detroit area I have traditionally been a rock and roll man, but have found that while driving my old trucks one artist seems to stand out in my play list...Johnny Cash! Am curious to hear what your number one old truck driving albums and songs are. Here's mine...

Album: Essential Johnny Cash
Song: A tie between Jackson and One Piece At A Time (from the album listed above)

Now that I have been living in Alabama for nearly 20 years, I've been dreaming of loading up the '67 or '70 C/10's with Johnny and June and taking a road trip to Jackson, MS!
