The world may never know exactly what South Carolina governor Mark Sanford did while he was AWOL this past week, but at least we now know where he went. A reporter for South Carolina’s The State caught up with Sanford in Atlanta’s international airport this morning as he returned from … Buenos Aires, Argentina. But didn’t his staff tell everyone just yesterday that Sanford was hiking the Appalachian Trail? And doesn’t that trail typically run through Appalachia? Yes! Apparently nobody not his staff, not his lieutenant governor, not the police, not his wife knew where Sanford disappeared to. But before you start dreaming up all the ways that a frustrated politician might relieve his stress during a secret trip to South America, rest assured that, according to Sanford’s untrustworthy and probably disingenuous account, he spent the week alone, driving along the coastline.
