This summer I decided to get rid of the substantial brush pile I had in the yard and built a makeshift brick oven to burn it all. I'm down to the last roughly 1/2 a cord of brush, and decided that it's all still wood, and began tossing punky, and old crappy but dry sticks in the wood stove last night... well folks, I wouldn't want to do this in January, but for this time of year... that crappy stuff still produces a nice amount of heat, and the stove burns it cleaner than the oven. So don't waste the brush folks... let it sit a few years, then burn it. I think I can heat the house through October with my brush pile alone.
