Have not posted in a while but really enjoying my smokette 009 for the past years. Just experienced another sonic boom when loading a 8 lb shoulder 2 oz hickory, 2 oz apple one bricket of kingsford charcoal set at 250 deg. Hit after 40 minutes in west suburbs of Chicago in 35 degrees. Seems to happen every time I smoke a butt with the extra wood I usually use for a butt (Maybe the charcoal???). Never happened when I do ribs with one once of cherry wood and one chunk charcoal set at 250 deg. Can't wait for the pulled pork which I plan on taking to my Nephews 16th bithday party. He LOVES my pulled pork and says it's his favorite meal ever!!
