GB, you brought back a memory that was great. At Hickam Air Force Base, we used to have an annual fair to support various child-oriented charities on the installation. Every organization manned a booth, and mine was the corn booth. It was done very much as you describe. Then, those of us who were working would grab ears of corn and run them around to the other booths, and we'd exchange ears of corn for nachos, burgers, fries, etc, untill all of the people working the booths had full meals. Great fun, and we provided money for day care and other child services.
