2. Triple D Nation: BBQ, Burgers and Beyond

On this trip, Guy Fieri is biting into burgers and barbecue. First up, he heads back to an O.G. Triple D barbecue joint in Oklahoma City to see what they're smokin' these days. Then, a burger biz in Roy, Utah, is flippin' patties for a third generation, and they've added some exotic meats. Finally, in Virginia Beach, Va., it's brisket and burnt ends like you wouldn't believe.
