The person at CBS News that posted this obviously did not look very closely at the image they used.
First of all, the story is Lansing, Michigan and the sign below the tweet is Malibu, California. Second, the sign is photoshopped or a hoax.
I really don't think that Malibu's sign says, "Cheap Nannies and Gardeners Make Malibu Great!"
Come on CBS! This is something I would expect from CNN, but not you guys.
