I'm sure there is a thread or an article on this subject and someone here will point me in the proper direction. I just completed smoking some ABT's in the 14.5". I filled the water pan with water at the beginning of the cook. The cook lasted around 2 hours with temps holding between 235-255. At the end of the cook, I noticed that the water pan was almost empty. I have read where cooks have been performed "overnight" for briskets and pulled pork. How does one maintain the water level in the water pan for these cooks without waking up every couple of hours to refill or is sand being used in these overnight cooks? Any info would be greatly appreciated.
