Hey all, I have a 12 lb brisket on the smoker along with some butts for a family reunion tomorrow. I put the brisket on at 10:00 am this morning and just checked the internal temp after about 5 hours and I was already at 175. I checked in muliple places with 2 different thermos and both are reading the same. I have kept the smoker temps fairly steady between 210 and 240 all morning. I was expecting this thing to go for 16 to 20 hours, what is going on? I'm freaking out a little because this is for a family reunion tomorrow. Is this thing going to be ok? Do I need to head out now and get another and toss this one? I need your expert guidance and opinions! Maybe I'm just being paranoid but I really need this thing to come out great. Thanks for your help in advance.
