Greg,
Ribs look great! Good job. I see you have the Weber 9815 thermometer on the top grate, gotta question for you about them. How often do you calibrate them? I had three of those, and all three of them calibrated when I bought them just fine. After 2 or 3 cooks 2 of them were 10+ degrees off, either low or high and eventually the third went bad as well. Maybe I got a bad batch, just keep an eye on them.
