I got the following from my son and thought it was worth sharing...
So I had a grill disaster a couple of days ago that I thought I would pass along as I think it actually makes an interesting sales pitch at the same time.
A couple of days ago I decided to grill a whole turkey breast on the BGE. I got the grill up to 350 and rolled the breast on to grill for about 2 hours (6:30 pm) until the internal temp was right. I went back into the house and proceeded to do some dishes, went back out after 30 minutes, flipped it, and flipped it again after the first hour. I double checked the vents were where I wanted them each time I went out to keep the temp consistent.
The next morning (7:28 am) I walked downstairs as I was fixing to leave and I noticed the back door was unlocked and slightly ajar. I immediately wondered if someone had broken in and went to look at the door, and when I looked outside I remembered! Expecting to see a black brick of what had once been turkey, I first looked to see what the temp was at and surprised to see the grill had only dropped to 200 over the 13 hours. I opened the grill up and again was surprised to see, not a black brick, but a dark caramel colored turkey breast. I touched it and it was still surprisingly moist and pliable on top so I took it back into the house for further investigation. As it turns out, only the very bottom ½ inch was inedible. The next inch or so was like dry turkey you get on a bad thanksgiving, and the rest was, surprisingly still moist. I carved out the good parts and have been enjoying turkey sandwiches ever since.
If this had been a gas grill, I believe I would have found two things that morning: 1) an empty bottle of gas, 2) the charred remains of what had once been a turkey. As it was, it was still mostly edible and I still had plenty of lump for the next attempt!
