Pit workers Larry Mitchell (L) and Willie Johnson pour vinegar into a large pot at Scott's BBQ in Hemingway, South Carolina, June 21, 2012. The Southern Foodways Alliance (SFA) and the University of Mississippi?s Center for the Study of Southern Culture made a stop at Scott's BBQ in Hemingway to complete the South Carolina portion of their ongoing documentary project, The Southern BBQ Trail. There are only 10 to 15 BBQ pits throughout the South that still use the old-time fire coal pit methods they use at Scott's according to food historian Rien Fertel and photographer Denny Culbert, who are conducting the study.
