A lucky number?
We live in dangerous times, and there have to be security provisions that we didn't need a few years ago, but you wonder how some of them are decided upon. Take this sign on my local mailbox. It has been there for many months, but this is the first time I really paid attention to it. How did they decide on 13 ounces? Is there something about explosives that makes 13 ounces a threshold for danger? According to this, it used to be 16 ounces. Maybe there is a security expert reading this who can explain.
