I just scored a nice load of english walnut and have a new load of oak comming next week, enough to last me the rest of this year and well into 2008, I fuel my smoker with nothing but wood, so far the walnut I've tried was very nice but I mix it with maple and oak, I might just grab all the walnut I can since it's free, it sure is pretty wood it's a damn shame someone knocked it down and left it lay the trunk was probally 40 inches across.
