So which was it...

...snow, rain, heat, or gloom of night that stayed this carrier from the swift completion of his appointed rounds??

Checks, bills and even a college acceptance letter from 2007 were among 20,000 letters found inside the garage of a Philadelphia postal carrier.

When the mailman missed several days of work in April, postal officials went to his Port Richmond home and found tubs and tubs of undelivered and unopened mail.

Some of mail found in the postal carrier's home dated back to 1997.

Investigators have yet to question the mailman because they have not been able to locate him.

Maybe he's gone into hiding, ready to ride again after the Postal-apocalypse.
