I recently acquired a new 18.5" WSM and i have a quick question regarding what to do with the left over charcoal after a smoke. Can you just leave it in the sharcoal ring? Will it draw moisture? If you take it out, what do you do with it to limit the mess? One last question, in the manual it says to leave at least one intake and the exhaust open to make sure no mold forms inside. I have been doing that, but seems like that would make your charcoal draw damp if you are leaving it in. Anyone with experience on this? Oh yeah, obviously, i plan on leaving this outside with the cover on when not in use. Its too handy to have it on my deck and not have to move it back and forth from patio to garage. Thanks!
