Re: U.S. Post Office's "standard war procedures."  Although I do not know
precisely what these entail, our main post offices have "boarded up" all
the inside mail slots/drops so that everything must be deposited in the
mailboxes outside; or, if a local postmark is wanted/needed, one must take
it to the counter to have it done.  The sign over the inside mail slots
reflects only: "Until further notice..." or "For the time being these are
no longer in service. Customers must use the outside mail drops...etc." No
furhter details are provided. Since this happened soon after Jan. 16th, I
surmised it was SOP (standard operating procedure) to safeguard against
postal bombs.  Where such "standard war procedures" regarding the U.S. Postal
Service might be found, I don't know, except I'm sure the Government Documents
librarians might clue us all in on where such information could be found!
