This morning I threw 4 7.5 lb picnics on the 18.5 wsm. My girls are home monitoring the temps as I have to work today. I can't wait to get home and see how this smoke is going. I have loaded it up with ribs before but never this many shoulders. They were rubbed last night with Jeff's rub and are cooking over kingsford regular with hickory chunks for flavor. Will report back when I get home.
