I'm told that the picture of the chip excavation pit was taken sometime during the second week of April. I'm also told that the concrete slab that was lifted which exposed the PB chips was part of a sidewalk or parking lot ... and that the top layers of chips underneath the slab were broken in two as if some attempt had been made to destroy them ... but that the lower bottom layers were of whole chips. It's anyone's guess when the chips were buried and how much protection the concrete slab and/or how much protection the top layer of destroyed chips provided the underneath large quantities of chips which appear to be in very good condition. I still haven't figured out the connection between Green Duck and Bud Jones (the original manufacturer) and why or WHEN these chips were sent to GD instead of BJ for destruction. Perhaps someone else may have some theories.
