I'm old enough to remember the Cold War. Although I'm too young to have lived through drop-and-cover nuclear attack drills at school...we only practiced for earthquakes...I do remember the occasional test blare of civil defense sirens.
Those things could wail. If anyone reading this is familiar with San Jose, I went to Sylvandale Jr. High, and the nearest siren tower was near the corner of Capitol and Senter...about a half-mile away. No ducking or covering followed...only teachers pointing out the obvious. "There they go again!"
I'm certain most cities have yanked out their sirens, but they're still hanging on in Los Angeles. In fact, one still lingers in front of City Hall. Why haven't they been removed? Indifference? Cheaper to just keep them rusting? Saving them for the next menace?
