Song meaning of Thoroughfare by Ethel Cain

Oh, Thoroughfare by Ethel Cain, a classic American tale of falling in love with the land of the free at a young age and wanting to see it all. And what better way to do that than hopping in a random stranger's pick-up truck on the side of the road? Sure, they've got a pistol in their pocket and torn-up clothes, but love knows no boundaries, right? As they travel from town to town, searching for the lover that only exists in their dreams, our protagonist begins to see their companion in a new light. For the first time since childhood, they see a man who isn't angry, and maybe, just maybe, he's worth sticking around for. The journey comes to an end on the coast, where they realize that love may not have been found, but they've found something even better - each other. And what's better than a tambourine- and scat-led jam session in the back of a pick-up truck with a stranger you met on the side of the road? Nothing, my friends, nothing.
