there's quite a few fraudulent organizations out there cashing in on the 'helping the vets' angle. It's sad to see. Encourages people not to donate, as they don't want to be bilked.
I'm thinking they would make excellent choices to find unexploded mines. Just them, a hot empty sunny field, and a whole lot of time to think about what they did, while wondering if the next *click* is a mine or a rock.
