" Dreams and coffee and sunrises make up the rhythms of the road.
Music is a part of it, too: the popular music on the jukeboxes and radio stations. You hear it constantly, in diners and on car radios. The music has a rhythm that fits the steady drumming of tires over pavement. It seeps into your bloodstream. After a while it ceases to make any difference whether or not you like the stuff. When you’re traveling alone, a nameless rider with a succession of strangers, it can give you a comforting sense of the familiar to hear the same music over and over.
At any given time, a few current hits will be overplayed to exhaustion by the rock & roll stations. In hitching across the continent, you might hear the same song fifty or sixty times. Certain songs become connected in your mind with certain trips. "
