Prepped an 11 lb Bone in Pork shoulder picnic roast for the smoker tonight. The plan is to start the picnic tomorrow late afternoon? I want to use my MES 40 with AMNPS pellet box but have had a hard time getting the pellet box to work properly (I have all day tomorrow to get it figured out). This is my first time cooking this meat I am mostly a rib/chicken kind of guy but want to expand my cooks. From what I have read it appears like this will take 16-20 hours at 230 degrees?
