Pancho (and Lefty) pointed me toward the highway.

By the words that were said;
I listened for those big White Frieghtliners
Travelling endlessly thru my head-
I stood with my thumb hanging
In the whistling Western wind;
I could not recall where I was going
Nor, where I had been-

The highway is tomorrow...
And those big-rigs are today;
I'll catch a ride, to find where I am bound
Just moving along my way-

I'm out there on that freeway
Hitchin' my blues away... far away;
Out there somewhere, ridin' that old road
Pickin' up the pieces as I go-
Out there on the highway
Hitchin' my blues so far, far away;
Goin' down a road
Just tryin' to lighten life's heavy load-
