Actually I have been told to make sure it got to 170 degrees, so that it was cooked, at which point I wrap it in foil and leave it on for a couple of hours (4-5 lb. shoulder) and not worry about it getting over cooked, because the foil will tend to keep the moisture from escaping. Everyone enjoys it and says outstanding, but I am not sure that they have been exposed to this type of bbq. I am just interested in getting that iconic smoked flavor, neither left nor right of that. Then I feel once I have accomplished that I can experiment for the purposes of putting my own thumprint on it. I will shoot for the 200 degrees mark, and thanks for the help.
