The terrorist attacks on the World Trade Center and the Pentagon on September 11, 2001 triggered a tremendous outpouring of patriotic symbolism across America. Many people filled their yards with flags, while others painted the exterior of their homes as flags. Inspired by the human stories of how this tragedy touched the lives of so many, Robert Carley set off across the country to capture the American spirit by photographing the American flag in as many forms as possible. Twenty years later, he continues to travel, photographing houses, trucks, and even hot air balloons, all adorned with the Stars and Stripes.
