I was definitely surprised this Christmas with a new WSM 18.5. I've been talking about getting one for several months now, but been putting it off. My wife works at the family hardware and ordered one for me. This will be my first time moving away from gas to charcoal and looking forward to it. Question: is it okay to use a WSM on a wooden deck? I was thinking maybe I need to buy some kind of tiles and create a heat/fire barrier, but thought I would ask some of you that are more experienced. I live in a townhome and not a good place to create a patio, which is what I would prefer.
