Mattapoisett PO employees are fabulous. However, whomever drives the mail truck down Meadowbrook Lane (not regular delivery serviced) should transfer to NASCAR. Just flew up the dirt, pot holed single car width right of way at 30-40 mph. 10:45 Saturday morning. Better check the axles and TG no cars coming. Frequent occurrence.
