OK here is summary of what people are using for creating smoke (!!!): Needles from _Pinus strobus_.(White Pine) bailing twin sugar wate burlap bags needles of Douglas fir _Pseudotsuga mentiesi_ cedar wood chips and some more staff that was not tested or not favoured. As for us here the favourite has been cypress tree "leaves". Slightly dry but not entirely. It produces tons of smoke is almost neutral in smell (slightly pleasant smell) and seems to work wonders. Of course cypress trees are in abundance here. Now here is one more for you: What do you use for your fire producing agent in your smoker? I will get this started. Now hold your ... keyboards: donkey manure!! Andreas
