Hello, here is my question. I followed all the steps for overnight smoking a 8.5 lb. butt. The egg stabilized at 250, but it was very very windy. At 11:00 pm meat was at 140 and all was fine. Woke at 8:00 am and egg temp was at 150. Meat was down to 125. Opened the vents cranked back up to 300 to finish. 21 hours total, fire was done and meat at 190 so I called it. Turned out awesome, but what went wrong ? maybe the change in the wind ? Also what is a guru ? Thanks.
