I am headed to a family reunion next week in Idaho, and I have been designated to smoke some butts for pulled pork. There are about 80 people, and I thought about 6 butts would do it (too much? not enough?). I had planned on taking my masterbuilt electric because it is easy, and I have four large racks in there. But I got to thinking that I could probably get 3 on each rack in the WSM, and that would be more fun to use. How many have you guys got on each rack before?
