The pork butt came out great! It sure did look dark because of the rub, I think, but tasted great. I used about 6 oz of Pecan wood at 235F of a 7+ lb piece of meat. I was concerned it would overcook overnight if I did it at 250F like Oakie suggests. It got to 178F in 8 hr. I turned it up to 250F and it took about 3 more hrs to get to 205F.
