Okay folks, quick question for you guys... Put the brisket in the smoker at 4:45am today...checked on it at 5:30a...things are good. Went to catch a few zzzz's, woke up at 7:15a - and smoker is cold - OUT OF PROPANE!! Internal temp was at 99 degrees...the brisket was mildly warm to the touch... I used my grill propane tank and fired her up again asap....I don't know when I ran out of propane..was between 5:30 & 7:15 sometime....an hour and 45 max....you think the meat is okay to continue...I'd hate to waste a $25 piece of meat!! Let me know!! Thanks everyone!
