Nigerian Prince has P.O. Box in TX

I received a letter in the mail the other day with a banner at the top that read “Important Retirement Plan Information.” When I opened it, I found a pretty lame excuse for a US Mail phishing scam. The cover letter included my name and address, and vaguely inferred that I have some unclaimed 401-k money sitting somewhere, but that they need some additional info from me to cut the the check, since the last one was returned (even though they some how managed to correctly address this correspondence). The following page asks for my SSN. Hahahaha. What!?? The return envelope goes to a PO box in TX. No where on this correspondence is there a phone number, a physical address, or anything else, besides the most generic fake company name ever: “FRANKLIN.” It is kind of sad for me to imagine some innocent unassuming little granny falling for this thing. I hope that scenario is limited to my imagination.
