Lock Your Box
Even if your house is secure, your mailbox can be an easy target, especially if it's right on the road. Identity theft is a growing problem, and your mail is an easy place to get all your personal info -- phone numbers, account numbers and even your social security number. If you don't already have a locking mailbox, consider investing in one. There's a small slot where the postman can insert your mail, but you hold the key.
