As a general rule, the barbecue biz is pretty low-tech, but we noticed that owner Robert Thompson and his wife, Linda, both wore wireless telephone headsets. Perhaps this be-prepared attitude is the secret to Thompson’s success. He insists that pecan is the correct wood and that twelve hours is the correct smoking time. Tender brisket and pork shoulder bore out his theories, although the meat could have done with a lot less salt in the rub.
