I just noticed this thread.
I have a bunch of fruit trees-we don't get much fruit most years but I do prune them and I use the wood for smoking. We're surrounded by pecan orchards, and I have a couple of trees, so pecan wood is easy to get. My neighbor chopped down an apple tree and an apricot tree, more wood for my smoker. And I bought a cord of mesquite firewood, if used in moderation makes a very tasty smoked pork shoulder. I need to get a bunch of apple wood-it does make a good rauchbier, and there are orchards within 75 miles, but I don't know anybody up there.
