For the second year, the summer issue of that excellent magazine the Oxford American has a “Southern Journeys” section — now online — with essays and reports from across the region. Among them is a haunting piece from Anne Gisleson, who, following the death of her nephew, takes a road trip with her two sons from New Orleans to “the End of the World” — the southernmost point of Louisiana. In another piece, Molly McArdle heads for the swiftly shifting sands of the Outer Banks, and traces the story of the region through the generations of one family who have called it home.
