This billboard will appears to show nothing but a dolphin on a blue background is sure to cause some double takes from drivers in Southwest Michigan.

The billboard shown above can be seen from southbound Sprinkle Road between Milham and Centre in Portage.

So just what does it mean? At this point, no one is quite sure.

There have been other mysterious billboards that have turned up in our area lately like the "Who is Denise" campaign which appears to have been for a State Farm insurance agent and the Out There Thinking series of billboards that  was a promotional series for the billboard company, Adams Outdoor.

So any guesses? What is the dolphin billboard promoting?
