Columnist Tom Greenwood of the Detroit News reports that a sign has been spotted "attached to an authentic Michigan Department of Transportation post on southbound Interstate 75 at the Oakland/Wayne county line." It reads: Welcome to Detroit. We hope you survive.

There's no word on how long this has been up, or for how long. Of course, fake road signs have been a popular prank for quite some time. There's the fake road sign project in Lyons, France, in which "105 street signs, realised by 47 worldwide artists, and just similar enough to real traffic signs to give one pause, have been attached to streetside poles around the french city of Lyon."

There's also the photoshopped picture of a Connecticut road sign that reads "Birthplace of George W. Bush. We apologize." Plus, the "Leaving Brooklyn. Oy Vey!" sign that was actually posted by the City of Brooklyn itself.
