Cooking styles can vary and be similar too. The NC folks I have hung out with in the past seem to like direct cooking over hickory coals..which is a preferred style of a bunch of Texas folks who sub out Oak and/or Mesquite for the wood ration. Have noticed that style is popular in the Hill Country and among those groups with German-Chezk ancestry. Bunch of the indigenous rednecks seem to have become addicted to using log burning offset creosote factories for some strange reason. Direct over the coals is the best there is.
