My brother in law just bought some property up the road from me and he has a couple smooth bark soft Maples (think they might be called Silver Maple) that he wants me to cut down and haul away. Now, my question is I have only burnt hard wood in my stick burners but would it hurt to toss in a piece here and there of soft maple? I know it wont burn as hot as a harder wood but I'll have a good amount of it. Or, is it just good for a campfire? Thanks
