I run my new Smokette on my wooden deck. I have always been a little cautious about the possibility of fire, but the Smokette runs very cool (on the outside) and there is no possibility of ashes falling on the deck due to the drain pan.
The other day, my wife bought some disposable aluminum oven liners at the grocery store for our oven. They're designed to be placed on the oven floor underneath the heating coil to catch anything that falls and makes clean-up very easy.
I discovered that these oven liners, turned sideways, fit perfectly under the Smokette. And, as a bonus, the oven liner has a 1/2" raised lip which will contain any spills or drips.
I'm not saying to use the oven liner in lieu of using a pan under the drain hole, I'm saying that the oven liner should greatly reduce (if not eliminate) the possibility of fire while using the Cookshack on a wooden deck (e.g. the large sheet of aluminum will catch any ash that might fall out of the drain hole, and the sheet will reflect any radiant heat away from the wood deck).
Just thought I'd pass along this tip.

Very good idea, Bear.
