I read the PB101 but was not sure on "smoking" on a gas grill and timing as well as some of the other questions (coffee grounds in rub, when to add wood chips, etc..). I have read post after post and you are correct... lots of great info.

There are no teens or kids. Some little 1-2 year olds so I am not gonna count them. Half are girls and some are grandparents that don't eat a whole lot. I want leftovers for tacos and\or sandwiches and for people to take home. I was gonna get a 8lb PB (Boston butt) and grill chicken as well. I figured 4lbs cooked would be plenty as that is approx 1/4 pound per person but would leave no leftovers. Maybe I'll get two 5-6lb PBs so I ensure I have leftovers and I won't run out.
Should I double Smokin Okies recipes for the mop and sauce? Not sure how much mop I will need to mix into the pulled pork and how much people will drizzle on their sandwiches.
