oh, yes the black walnuts, yep, this is the year of them. seems like they alternate . So we are getting the banging and popping of them falling. They land on the grill, then there is the ping, they land on the roof and roll down noise. Then there is the walking on a sloping path and hope to avoid them before you roll on them and fall. They don't burn well either. As said earlier we use a variety of equipment to get things up. If we were to bag them, leaves or nuts, I would have to use up 10 boxes of bags, and then that is more plastic to mother nature. So again we have a huge huge leaf pile, actually two of them, it takes a good two years for the pile to break down.
