A lot of good advice to digest Mark. I don't know about anyone else here, but I consistently get lose 50% going from pre-cooked to finished pulled pork. So you may be looking at somewhere around 40 lbs. when you're done which means about 5 oz. per person (if I did my math correctly). If that's the only protein, that's cutting it way close, at least in the crowds I cook for.
