Gary Massa submitted this photo, taken in Corolla, North Carolina in July. Writes Massa, "I took this (silhouette) picture of three wild horses running wild on the gorgeous beaches of The Outer Banks in Corolla, North Carolina in July. Observing these horses running on the beaches for long periods of time and following them around the many miles of beach area set aside for them to do so was an amazing experience! They receive no food or any type of assistance from anyone. Their survival depends solely on their ability to endure!"
