I've always thought you can tell a lot about a person from the bumper stickers on their cars and what is hanging from their rearview mirrors. My favorite thing to do while sitting in traffic is looking at people's cars and trying to learn what they are about and what is important to them.
Take me for example, I'm a private person who doesn't make my true feelings known that often. I also like things clean and simple so I have no bumper stickers and the only thing hanging from my mirror is my parking permit.
From crosses and dice to beads and baby shoes...what is hanging from your rearview mirror?
