I have access to a mountainous burn pile out behind the local John Deere implement dealer. Lots of pine and cedar, of course, but I’ve also found some hardwoods (oak, ash, poplar) mixed in among the dross before. Plan to gather up my safety glasses, cordless saw and extra battery, hammer and pry bars and go see what I can find tomorrow.
If successful, I’ll post a picture of my haul.
