Heading west out of Hue, I began the journey into the wilds. I was excited about my first stop – a small town called Khe Sanh. It may not ring a bell if you’re not Australian, but the song is one of our unofficial national anthems, along with Waltzing Matilda and the one about being from down under. We know more of its lyrics than of the real anthem, by which I mean about a verse and a half. Anyway, Khe Sanh awaited. I felt like I was on a pilgrimage.
