Interesting. You collect scrap wood, and also discard whole trees! What's wrong with pine? Nothing. I'm burning cut up pallets, they burn fast and hotThe island does not have a lot of hardwood trees, so those that exist are carefully guarded and cared for. We have a great deal of black pine, and I lose one or two trees a season in big nor'easters, which I cut up with my chainsaw and stack, or I have it carted off to the dump. I can't imagine it's good to burn.
