I happened to be at the airport this weekend and saw a big, green, almost-mailbox looking thing that I had never seen before. Knowing that in this day and age there is no way they would adding mailboxes to airports, I checked it out, and was surprised by what it actually is.
It is called an "amnesty box." It's basically a safe place people can ditch their leftover pot (or other drugs) before heading through security, where it's a no-no - even in states where it's legal.
The boxes are bolted to the ground so there shouldn't be a theft issue, and they are emptied by a paid contractor.
I just want to know what was wrong with the regular trash can?
