I cooked for a party once. I thru in a couple of flats on the rib side running about 325 temp. The flats were place about 8 feet from the fire box next to the chimney. I pulled the flats at the 6 hour mark, the bark looked dry and charred but when I sliced into one I became a believer.
never been a horse that couldn't be rode, never been a man that couldn't be throw'd.
