This is yet another song by Woody Guthrie---#1001.
He had heard about those BLUE HIGHWAYS William Least Heat Moon Sun Stars was always writing about. (The ones where the cows got into the ink supply and mood indigo from that day on.)
Right then and there woody wrote his song about "I'm Goin' Down That Hot Dusty Woad".

Just figured you all'd like to know the real story.
On the American scene we all pretty much learned it from Joe Hickerson's LP for Sandy.
