Niklas Folley, 4, of Cary, N.C. plays with a waterhose at the Nature Play Space at the Prairie Ridge Ecostation in Raleigh, N.C. on Thursday, May 1, 2014. He typically spends at least 2-6 hours playing there on Thursdays with his mother, Tina Folley , not seen. As part of the North Carolina Museum of Natural Sciences, the facility's mission is to enhance "public understanding and appreciation of the natural environment by providing an outdoor learning space while acting as a model for renewable and sustainable energy."
