I wanted to make a book of some kind. And at the same time, I—my whole attitude about everything came out in this one phrase that I made up for myself, which was “twenty-six gasoline stations.” I worked on that in my mind for a long time and I knew that title before the book had even come about. And then, paradoxically, the idea of the photographs of the gasoline stations came around, so it’s an idea first—and then I kind of worked it down.
