As for the OP's story. I don't really get what is being said. UPS delivers everywhere. Perhaps there's a few remote places we don't? But for the most part, we go further than the Post Office. The USPS often gets to deliver a whole area by just parking at a collection of mailboxes at the beginning of a street. The type of street/road that is often a pain to get to each house, or a private road, or sub-division, or whatever. Guess what UPS has to do? Go to each door step. WE do the last mile, not the Post Office.
