I’ve never been able to, I should say. That is, I’ve never been able to write the kind of book I am talking about, or imagining, even if I have always, on these trips, ‘gathered material’ in some sense of that phrase. I don’t even know what sort of book it would be, were I to in fact write it. Which I suppose is why I’ve resorted to whatever book this record is, that you are reading now.
