You never think that you need a whole lot of security when it comes to your personal mailbox, but you do. These days you cannot trust many people when it comes to your mail. There are systems in place that allow your mailman to still get in the box, while keeping the peace of mind that your stuff is safe. My mom had some stuff stolen out of her mailbox and she was so upset she went out and found some locking residential mailboxes to keep everything locked up tight. She now has told all her friends and they have done the same.
