If you have pot holes in front of your mailbox, USPS may hold your mail and/or close your mailbox. Our new mail carrier is asking community members to proactively fill the pot holes before she starts delivering complaint notices. The best rock for this is 5/8 minus, which can be purchased at Maillards Landing Nursery by the 5 gallon bucket for $2 dollars. Miles Sand & Gravel also sells gravel.
