Newbie here. I received my WSM 3 weeks ago. Made a few mod's like putting on a temp gage and I'm doing the clay pot base mod instead of water. Does anyone think that the water pan really helps keep the food moist or is it strictly for the indirect cooking purpose. I saw Alton Brown smoke something and he made a good point that water or moisture in the air will actually block smoke from getting into the food. After thinking about it I kind of agree with that. Thoughts from the pro's on this board?
