You stand barefoot on the rocks, the bottom of your feet toughened to a calloused “summer feet” leather, as the warm summer sun sets and the juice of a ripe watermelon runs down your chin. You watch kids jump their bodyboards into white water, waiting for the energy of the ocean to lurch them forward, then steady their speed and send them gliding toward the ankles of parents at the shoreline. You leave the beach and retreat to the shade of your quiet campground in the Pine Barrens.
