First, pardon me if I'm not doing this right. I'm new to the forum. I bought a whole pork shoulder to smoke for the holiday. It has the skin on it. Do I just put rub on the skin, score the skin then rub it, or what for the best results? Also, it's about 9.5 lbs. I figure about 14 to 15 hours at 225 will be a good guess. Does that sound fairly close? Thanks.
