Even though most people were disconnected from [travel ban], the moment amplified a fairly massive and somewhat irrational fear that exists in the populace at large.

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.

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.

At first Disco Night wasn't meant to be a book, although I'm always thinking about that in the back of my mind. It started off as a series of exploratory road trips that I was doing with Christian Hansen, who I dedicated the book to.

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 realized how little I knew about my own country. I had grown up in the suburbs and, after college, I moved out of the country, so I didn't really know the place well. When I started following soldiers and their families back home, it provoked a lot of the questions about who we are as a nation, questions I realized couldn't be explored through the more limited framework of looking at the military at war and at home.

I began to explore America in more general terms. I really started this work in 2009. I got the bulk of it done as I was easing out of Disco Night.
