Post Office Hopes New Mowers Will Deliver

The U.S. Postal Service is bringing in cattle to trim grass at its main Louisville post office. Four steers or cows, or maybe even beefalo, will begin grazing a 2 1/4-acre grassy area around May 1.

An internal memo says officials cannot scientifically predict how effective the cattle will be. But bureaucrats forecast a savings of 210 employee hours, or $4,130.01 a year. That assumes, of course, that neither rain nor sleet nor traffic noise will stay the trusty bovines from the swift depletion of their appointed grounds.
