Hi there, new to posting, but lurk often. I have a WSM"bullet" smoker, smoking 2 15 lb pork shoulders (actually, they are split into 4 roasts after pulling them from the pack in which Costco packs them in). Fire was rolling, got them up to 163 at about 2am. Checked temp again at 3 and 4, holding steady. However, I fell asleep with insufficient fuel, apparently, woke up and fire was out, temp had dipped to about 145 internally. Just got fire rolling again, are they safe to finish then eat? I am feeding a lot of people Saurday, don't want to make them all ill! Thanks in advance, folks.
