I just read an article that said about $400,000 a year in change is left at TSA security checkpoints in US airports. Someone suggested they donate it to the USO. I love this idea and think it should be expanded, or should I say solicited. I would support TSA having donation stations before and after the security checkpoint. And keep a running tab, a "thermometer" that shows how much that particular airport and the nation contributes. They might get a lot of chips at McCarran.
