I am still covering conflict to some degree. I was back in Iraq. I've covered quite a bit of the Israel and Palestine. But I'm not doing it with the kind of intensity I was before and I'm not seeking out the front line and the kind danger that comes with being at the edge of the war the way I used to.

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.

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.

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 think a lot of the work I've done and a lot of the work I'm going to do in the future still ties to 9/11 and the fallout from it.

[The Middle East conflict ] just kind of ran its course for me. For a long time I could justify doing it to myself, no matter how irrational it was. It was important to me and my work. And I just don't feel it in the same way any more. When it comes up and it's important to me, I'll do it, but more out of sense of duty than desire - which used to be a big part of it.

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.
