In my couple of days on SMF Ive seen a bunch of people talking about the a-maze-n smoke tube and the mailbox mod on their MES smokers. I want to know. What's the point? What makes them so good and why do people like them so much? I see no problem with periodically adding a handful of two of wood chips. It gives me a chance to check my meat and mop while I'm out there. It also isn't a big waste of wood chips either. Just a handful of two every couple hours. So what's the purpose? Thanks for the info.
