Civil Defense--Filling in the Gaps Traditional Geocache

One of a series to fill in the gaps between Downtown caches. Parking is scarce or prohibited near most of these caches.  If you find a good parking spot, take it and do this series as an "urban hike."

Growing up in Los Angeles, I remember the last Friday 10:00 a.m. civil defense sirens going off.  I always thought that if the Soviets were going to attack us, the last Friday at 10 o'clock would be the time to do it.  Everyone would think it was a test.

The sirens have long been silent.  The system no longer works.  It was disconnected in 1985.  However, most of the sirens still dot the landscape, monuments to the Cold War.
