I discovered with disgust that John Kelly’s April 1 column about “Washington’s first subway” was a prank [“A fool’s errand: Exploring the Mole Way,” Metro]. I have been a journalist for 25 years and am saddened to find that The Post has stooped to yet another low by printing fictitious copy.

Have you become immature college journalists? Apparently so. Your credibility is waning for a number of reasons. Don’t add to your problems by deliberately making stuff up.
