I figured that many of you have cooked for a large group of people before. I am having a party next weekend where I will have approx. 40 guests (27 adults). I am planning on serving pulled pork at the main dish. I currently have a 6.5# Boston Butt in my freezer. Do you think that I would have enough pork if I got 2 more butts that are approx. the same size? I may go larger for the potential leftovers.
