I have wood from an old apple tree at the moment.. I'm guessing it will last me through the summer.. I'm already starting to worry about where I will get my next load. I have a cabin on the Missouri river in Iowa.. there are lots of dead trees around for the taking. Up until now I've never been really concerned about what types they are. I can easily identify cottonwoods and elms and the like. What good smoking trees are indigenous to the area that I should look for? I can pretty much say there aren't any fruit trees growing in the wild out there so what else can I look for?
