100 Words on a Very Mysterious Blue Plastic Suitcase

On the way back into town on the elevated portion of South I-110, near the Mohican Street exit, I saw a billboard depicting a blue plastic suitcase that said “$10,000 Reward if recovered – no questions asked.” What could be in that suitcase that would cause you to get a billboard made? The billboard rental alone is a couple grand. Would you put up a billboard to retrieve something illegal? I love the idea that there is a blue suitcase sitting somewhere in wilds of North Baton Rouge, containing something worth a lot more than $10,000 to some very nervous people.
