That situation, my answer to it and their predictable responses has happened at least 10 times on that page in the last year. When we moved out here, within a few months, some fool went down the row of boxes, opened them, scattered the junk to them mail on the ground and took what they wanted. That was all I needed to go get a secure mail box, set a post in the ground, and install it.
I post up links, explain that you only need to protect the things you care about and there is no other answer. The theft can't be stopped unless you want to stand guard.
This is typical of how folks do their mail boxes out here.

I don't understand why it is so hard to figure this one out.
