The first wave of firewood arrived shortly before the heatwave. Conquering Mt. Cordwood is a family affair, and it has to happen quickly, as more is on the way.It takes a little over 4 cords of wood to heat our earth-sheltered house. We don't use any other heating source. Some years we cut more than others, but the Big Guy and I mind paying to have it delivered far less than we minded paying for oil in our old house. We know the woodcutters, and it's nice to have the bulk of the money coming into the community.
