So I was at my local supermarket today and I originally went for bread but whenever I stop by the market I always go to the meat section first. Anyway, while I'm there staring at the meat a person next to me starts complaining to me about the lack of meat selection and then somehow we start talking about making tri tip and I asked him if he smoked his and he told me that he just uses an apple flavored wood plank on his grill and smokes his tri tip that way. In your humble opinions, what are the benefits of using a wood plank on a grill as opposed to using wood chunks in a smoker?
