This image was made during an amazing trip to the Turkana region in north Kenya. During the day we had seen these boys herding their families' livestock - camels, donkeys and goats - to grazing sites and waterholes. As the sun set, we came across the boys again. Their day's work done, they were at play, whooping as they dashed across the dry riverbed - being boys once more after a long day doing 'men's work'.
