Long story short, I put a butt on last night. Had the weber at 250 and fell asleep around midnight. I woke up around 5:00 and charcoal had burned out. Temp on the butt was 135. Got the heat going again and finished the cook at a temp of 205. The meat temp was in the low 100's when I fell asleep and I do not know how high it got, or how long the fire had burned out for. The wife is afraid to eat it, but it looks good. Checking for some more advice.
