Through a twig archway in a pocket of the forest, a group of children played in the dirt and on some old tree stumps. In the background of their play space, known fondly as secret spot number two, stood several stick structures, remnants from the past year. Last summer, the older campers at Felix Neck Wildlife Sanctuary’s Fern and Feather Day Camp built the forts for their traditional Thursday night sleep-out. This year they are territory for the younger kids to explore.
