My roommate, an Iowan by birth, theorizes that field rocks hypnotlze farmers into putting them on top of fence posts so the rocks can receive solar radiation, a key ingredient in their growth. Is this correct?
———- from Chris Jacobs of Woodbury MN
He’s close, but still no cigar. The fact is, rocks sit on top of fenceposts because they’re natural voyeurs and the sight of a red winged blackbird or a combine driving by proves so stimulating that the rock actually mates with itself, causing sand to spill from the top of the post. And as everyone knows, sand is actually rock seeds. In a remote, unpopulated place like Iowa, there’s so little to watch that rocks rarely reproduce. Hence, the soil is neither sandy nor rocky!
