I'm smoking pork shoulders for my Son's wedding. We are expecting roughly 150 guests. I'm figuring about 65 pounds uncooked. Does that sound correct? I did a practice run last night to see how long it will stay hot in a cooler, in about two hours it only dropped about eight degrees. I figure I can smoke them the evening before into the next day and hold them until the reception without reheating. Does this sound doable?
