I got 15 adults fed with that one with sides. No leftovers! We had 45 including adults last weekend. Came home with about 3 lbs. of pork. But I didn't pick the bones as well as I could've. Enjoy and Happy Birthday.looks awsome, i've been wanting to do one on my uds ever since i saw your 21 pounder. how many can you feed from a 20 pound or so piggy? my 30th birthday is coming up and i think it would be great to do something like this.
