Does anyone have/know of wood that throws off sparks? I am refering to when I open up the door to reload. The other night sparks where coming out. not that you could see them until they got enough air, try near my face. I have heard Locust will spark when opening the door and lots of air gets to the coals. Not sure if thats what i have but im curious as to others expirences. the wood charts I have seen pretty much say no wood sparks, I find this hard to believe.
