John, a lot of people (myself included) use a method called 3-2-1 with St Louis spare ribs or 2-2-1 with baby back ribs. The first number refers to the number of hours on the smoker unwrapped. The second number refers to the number of hours wrapped in foil and the third number is an hour back on the smoker unwrapped. Dave appears to be using this method for these ribs. In that 2nd picture he has the foil prepped for the wrapped stage with what appears to be a little honey, brown sugar, and butter laid down to lay the ribs down on (meat side down) and wrapping them up for the 2nd stage of the cook. This is an easy way to get consistent results when cooking ribs. Dave, feel free to correct me if I am wrong. 8)
