Hey guys and gals. New to the forum. Glad to be here. I've searched high and low maybe I can't find the right keyword lol. When holding a temperature in the OSS and the ribs are going into the foil. Can I burn any kind of wood during that 2 hour period as I'm not generally smoking. I've got some scrap 2x4s and such and some old firewood kicking around. Vs using my apple or cherry wood. The firewood very inexpensive to use where I live. Maybe even just use charcoal? Thoughts?
