Was LAS a butt felt comfortable with the stability of the egg so I went to bed. When I woke up the egg was at zero and internal of the butt was 92. I used the last of the bag but I would have had enough to finish the butt If the fire didn't go out. What had happened was the lump burned up through the middle. Well i stirred the lump and got my fire going again. Got the butt up to 182 and the fire was gone no more lump. I said no problem I will just finish it in the oven. So I foiled it and stuck in the oven at 210. Well it pulled good but it was super dry.
So lessons learned. don't use the last of the bag to do a low and slow.
Set an alarm clock (since i don't have money to buy a guru yet) to wake up and check on it.
Don't put it in the oven if you already have reached a safe temp. I should have sliced it at 182 and moved on.
