We have rural mail delivery, and our box is about a mile away. It is serviced by a contract carrier, not the USPS itself. Occasionally we notice that the carrier takes a long weekend and delivers nothing on a Friday and Saturday to go fishing or whatever. To get packages, we have to drive 20+ miles to pick it up at a depot, so when UPS and Fedex drop the packages in the mail for delivery, it definitely delays delivery. Most of the time, the parcel services deliver to our door. It is an innovation that occurred when Amazon became prominent. Prior to Amazon, Fedex particularly would "save the packages" for a week or more before delivering to our area. Now the volume has gone up. Amazon now has their own plane fly into Anchorage, and that actually slows down delivery out here, although it allegedly services Anchorage better. Does anyone remember Newman???
