I saw a show the other day where a BBQ joint did 18 hour smokes. I just wonder if someone has to tend the Q overnight? All wood smoker was used. Any idea how to make this work without waking up every 2 hours to tend the fire and keep the temp right? I did an over-nighter once but I had to get up to tend the fire and that made me pretty much shot for the crowd the next day, although great raves about the Q.
