One of the ironies we encounter everytime we drive north-by-northeast, either during 2006 when bouncing back and forth between temporary and permanent homes in New Orelans and New Jersey, respectively, or more recently as Gustav evacuees:

There's a huge parking lot of unused FEMA trailers ~ hundreds of them ~ right alongside Interstate 59 near Laurel, Mississippi. We taxpayers paid for 'em, some company made the deal and collected their price, and the trailers have been sitting unused at least since early 2006 while hundreds, maybe thousands, of displaced families could have taken temporary shelter in them.

Good luck recouping those overpayments. I have a hunch that more effort will be put into dunning flood-victim families for one to two thousand "overpaid" dollars apiece than into trying to hit up any campaign-contributing contractors for hundreds of thousands, even a million or two, each.
