Well, it doesn't matter where I go, the billboards seem to ever increasingly become blank.

There's a saying that money makes the world go around, so if the money is all gone, does the world stop turning? No, but people lose jobs and stop buying goods, then the manufacturers and retailers downsize and lay off. Another area that get's cut is advertising. If you've been driving your Mopar around lately you've likely noticed the same thing that I have. More empty billboards than ever.
