I just took it off the smoker at 12:30 (3 hours earlier than I really wanted to). That means it will need to sit for about 6 hours. I've got it nicely wrapped up in the cooler at the moment, and I'm going to check it at 4pm. If it needs some love, I'll throw it in the oven at about 200* in the foil with a little bit of beef broth to help with moisture.
Thank you everyone for the suggestions! We'll see how this goes.
