Key to the highway

I got the key to the highway, and I'm billed out and bound to go
I'm gonna leave here runnin', 'cause walkin' is most too slow
I'm goin' down on the border, now where I'm better known
'Cause woman you don't do nothin', but drive a good man 'way from home
Now when the moon creeps over the mountain, I'll be on my way
Now I'm gonna walk this old highway, until the break of day
Come here, sweet mama, now and help me with this heavy load
I am due in West Texas, and I've got to get on the road
I'm goin' to West Texas, I'm goin' down behind the farm
I'm gonna ask the good Lord what evil have I done
