Very interesting Bam, as I read that a water smoker wouldn't reach a high enough temp with the water pan full to do ribs in a timely manner. Thus I foiled my water pan to catch drippings, and left it dry. Still, my ribs killed, and I believe I will be doing another batch this weekend. The combination of the sweet rub bark and the carolina mustard-Q sauce was great, and I've been dreaming of it ever since!
