I was taking all prints and I brought them to the Magnum meetings, trying the old Josef Koudelka trick: Give them to photographers, who are getting bored during the talks about the economics of the agency, to look through with a pen. They'll separate them in two piles. I started to find the core pictures that people seem to relate to.

I went out to cover the wars in Iraq and Afghanistan fundamentally [in Buzzing at the Sill] because I was interested in war as a notion and in experiencing it. I was interested in history and how societies form. I was interested in the recent history of what had provoked these wars. So when I finally got out there, I was really seeing the wars through the American perspective, much more than through being embedded with American soldiers and Marines.

[Buzzing at the Sill] deals with the margins of America, a lot of parts unseen. Well, parts that are seen and familiar to a lot of the populace, but unseen when it comes to the parameters of what mainstream news and popular culture and Hollywood reflects.

Buzzing at the Sill is from a Theodore Roethke poem called "In a Dark Time." I'd heard a small part of it in a play, a sort of sci-fi play about morality in a virtual reality universe. Nothing to do with the book precisely, but it was a great play.

Nothing is over until there's something more decisive than your own thoughts.

The travel ban that was imposed by the [Donald Trump] administration is a very direct reverberation of 9/11.

What I was doing for those assignments wasn't always directly tied to what I was doing for myself, but it gave me the space to photograph. I started getting assignments that dealt with my own interests and made some pictures in that direction.
