Each spring, the start of the major league baseball season brings a fresh slate for teams and their fans, from the Green Monster in Boston to Dodger Dogs in Los Angeles. But as summer fades into the shorter days of autumn, the memories of a season past extend beyond the field, reaching into the slanted seats of the upper deck, onto the crowded sidewalks in front of a ballpark.

Photographer Ray Whitehouse, a graduate student at North Carolina, traveled approximately 18,000 miles over 85 days to visit the 30 major league ballparks to try to capture the game-day experience in each of these cities. The opportunity to watch each team on its home field, in front of its home crowd, kept Whitehouse on the road at one stretch for 43 days as he visited 21 stadiums. At each park, he purchased the cheapest available ticket. Armed with two cameras, he set out on a simple mission: to compile a portrait of America through a pastime that has so strongly influenced its identity.
