That’s what I would do, cut back on some of the rural deliveries (Say within a mile radius) and cut postal service to 4 days per week.
Why is no one talking about urban door to door delivery? How much does that cost?
I lived in a trailer park some years ago and had a block of PO boxes at the end of the street that worked fine.
Some of these closures here will mean a mere 30 mile round trip to get the mail will become 50 miles or more.
You have to have acreage to ranch or farm here, and that adds up to distance from large towns.
