Watched a video over the weekend of a Pitmaster we've all seen on TV showing that you can do a Brisket in your backyard without spending half a night and all day on. He smoked one that was 13 pounds at 400. after 3 hours wrapped in butcher paper and a hour later checked it and it was 209 IT. When he cut into it the tenderness was great and juicy. Is this possible or was he trying to pull something? I typically go around 275 and gives me about a hour a pound. Thanks
