As a regular reader, I spotted the article on the cutback of service for residents of Phillips and the Cedar-Riverside neighborhoods.
While I'm still working at the main post office in downtown Minneapolis (over 33 years now) and having delivered mail to both the Powderhorn and Phillips neighborhoods for a lot of my earlier years, I may be in a position to add to the information that Sam Adams gleened from Jim Ahlgren and others at the post office.
Employees (both the clerks and carriers) that I have talked to don't recall hearing anything about the Postal Inspection Service being involved in this "mixing" of "unregistered" and "registered" mail issue. I think that I would ask to see these regulations.
"Ahlgren bristles at the suggestion that the Postal Service is neglecting the Phillips neighborhood." This line caught my eye right away—don't think for a minute that the post office is sending all of the new apartment and condo owners from the new development in the Warehouse District up to the Annex looking for their "left mail." While changes may be due in the future, I would expect that the residents will have a say about what direction and distance and hours will be involved in their retrieval of their mail. Meanwhile, the Warehouse District is finding their mail at the very location that Phillips and Cedar-Riverside residents cannot utilise.
