Family Ties

What is with the stupid little stick family stickers that I see all over the SUVs of Bakersfield? Now, these have been around for a long while, but I never noticed that I only see them in Bakersfield. I never see them in Sacramento or the surrounding area. You may say this is a result of spending most of my time around a college campus where there aren't a lot of family owned vehicles, but I also spend a lot of my time around soccer fields, where there are a lot of families. Did some car dealership decide that every family that buys a new SUV needs to have a sticker of them on their back window?
