The American dream takes on new meaning in photographer Eliot Dudik's series Paradise Road.

Through the images, Dudik takes the viewer on a journey across the U.S., from empty grasslands to suburban lawns, from dirt byways to mountain valleys, all along different roads named Paradise Road. Each photograph unveils a different view of a potential paradise through expansive landscapes and stoic portraits of people he meets along the way.

The quiet of the late-winter morning is interrupted by a staccato of gunshots.

"Military drills," shrugs Kim Seung-ho, 58, the director of the DMZ Ecology Research Institute, a nonprofit organization that does research on the wildlife in the Demilitarized Zone, or DMZ, which is the border area between North and South Korea. A thick blanket of fog seeps over the forested hills on this late-winter morning as Kim stands, searching the horizon for birds, on the bank of the Imjin River just north of Paju, South Korea.
