I don't get much Elm here in my area of PA., but one time a friend gave me a couple of dry pieces of it to burn, and it burned like that old firewood poem said "Elm wood burns like a churchyard mould, even the very flames are cold", but I see on occasion some of you fellas singing Elm's praises. Are there some species of it that aren't good for fuelwood but some that are? Just curious....
