Great first smoke, Bigboy! Solid method for an overnighter. I'm going to use something like that next time I do one overnight.
Bob, a butt is a fantastic first cook! They are forgiving (dang near impossible to mess up), and very satisfying to have a great result on a first smoke! Check out the pork section for our posts, and find something that looks good (lots of choices now). Several methods and recipes out there to suit your taste, and butts are pretty easy from start to finish.
