I was splitting some red oak today, and there were a few pieces that were obviously splitting different than the rest - lighter in the center and very "stringy" when split. Relatively light, too, when compared to the oak. A friend suggested it was some type of gum, but dad informed me that it was sourwood. http://en.wikipedia.org/wiki/Sourwood Anyone here burn it? If so, what are your impressions? I may chuck a few pieces into the Endeavor tonight.
