Road Debris

I have been seeing a significant increase of road debris down here in Louisiana. I'm not talking about an occaisional cardboard box, but ice chests, ice chest tops, sofas, tables, mattresses, kitchen appliances, bags of aluminum cans that fell off of a vehicles, and cans all over the road, lumber, pipes, I could go on, but you catch my drift. these are objects that could cause a very unpleasant experience on what started out as a relaxing ride, whether you actually hit them, or they are hurled at you by the vehicle in front of you.
Have any of you guys seen an increase of road debris in your state ? Anyone have an unpleasant experience with road debris?
