Yesterday I went to a local Lowe's for a bag of lump and snagged 6 ten pound bags at a reduced price because the bags were busted. Today a neighbor called and asked if I wanted some maple for firewood, it turned out to be mostly rotten. But he also had an apple and a pear that were to be wasted in an upcoming construction project. He helped cut up and load the trailer with pear and the apple was just the right size to drag home with the tractor. Should be a long term supply of chunks for my UDS-30. I've been using apple bought from a smoker wood supplier, haven't used pear before.
