Hate to say it, but this box in the Los Angeles area appears to be MIA. This is the second
message I've received on this:

Message:
Hi, we went out today to find your box, but discovered a freshly dug hole behind/under
the flat rock, and no letterbox! How rotten! I'm sorry!

Drag-ola. That box lasted about as long as Clay Aiken's career.
