I am hosting my wife's birthday and I'm making BBQ. I will have about 50 people give or take there and I will provide the BBQ and I want to know how much I will need. Right now I have 3 racks of baby back ribs and an 8lb shank ham. I am planning on getting 3 more racks of ribs and a Boston butt to do pulled pork. Do you think I have enough,to much or not enough.
