Introduction: Gregory Elder tells of growing up on the Atlantic Coast, where he spent long hours working on intricate sand castles. One year, for several days in a row, he was confronted by bullies who smashed his creations. Finally he tried an experiment: He placed cinder blocks, rocks, and chunks of concrete in the base of the castles. Then he built the sand kingdoms on top of the rocks. When the local toughs appeared (and he disappeared), their bare feet suddenly met their match.
