You're right. Nassau St. is the main drag in Princeton. I find it hard to believe the public mailboxes on this street were not tested after the news last year. Maybe it's just that we're only being told about this discovery now.
The article says the found the mailbox on Thursday night. I can only hope it's a false positive. I do know that when anthrax hit the Trenton Post Office, my daughter's RA doc told her not to even touch the mail, no contact whatsoever. For months, her long-suffering fiance stood outside her window, holding up each piece of mail for her to see. If it was a bill, she wrote a check, gave it to him later and he mailed it for her. I'll allow myself some borderline hysteria, but I do know her RA doc was so so right.
The mailbox was found on Thursday night in Princeton, New Jersey, and has been sent to a U.S. Army facility in Aberdeen, Maryland, for forensic analysis, U.S. Postal Service spokesman Dan Mihalko told Reuters.
