Well, I'm trying to clean up all the branches that came with the dead tree that was cut down. I'm attempting to burn a good part of the little 'sticks' too. My first impression is that it is a lot of work for not much heat, but I have to clean it up anyway and the other way is to just haul them into the woods. I might give up, since it really is a lot of work. I wonder how much stuff falls from trees naturally in the course of a year and how much of that could be used to heat a house, albeit with a lot of effort.
