We are putting on a back to school barbecue at our church this Sunday, and me and another guy are smoking the pork butts for it. We're expecting around 200, and we're using bone-in pork butts. The question is, what would be a good estimate for how much we need to make sure we don't run out. We've got 40 lbs right now, and I'm thinking we maybe need to double that. Neither of us have ever done this for more than about 15-20 people before. We plan on doing most of the smoking on Saturday, so we're ready ahead of time. Give me your thoughts please. I was just guessing about 1/3 of a pound per person, but I want to make sure we don't run out, with the expectation of quite a few visitors.
