Well stated, shalom. It's been said that a man travels the world over in search of what he needs and returns home to find it. I think we find this song's travelers in the middle of that journey, not quite knowing who they are or where they're headed in life, but taking pleasure in simple vices like hitch-hiking, cigarettes, and junk food, and doing their best to enjoy the ride. It reminds me of my college days when I was in the same place - a life filled with freedom and fun, but a longing for more meaning and purpose that I later found in the very life I had been running from.
