Update: fired up the smoker about 9:30 Friday night and put the butts on at 10:45. Went to sleep and the wsm was solid until they came off at 11 Saturday morning. Into a preheated ice chest and to the camp I went. Pulled them at about 7pm Saturday night. They were still plenty warm. Everyone loved it. Dove count was 110 between all the people we had. Great day!
