Nate - Some sage advice I was given when I first started asking for help here on the forum about ribs - If you are smoking say several racks, and you are sure they are done, leave half on the smoker for another 30 minutes to 1 hour. Until you are sure of your smoker, it will amaze you but the last half to come off the smoker will be much better. Good cooking to you - It's always your temp guage thats right, it's your gut feeling - Bob
