The neighborhood siren was cool, except if you lived under it in the neighborhood. As a kid, told me that was a good time to turn on my scanner... My town fire district was the size of Manhattan, 22 SQ miles, there were 5 sirens throughout the neighborhood. When brush fire season was in full bloom they almost never stopped blasting...One neighbor I heard tried to chop one of them down...Then there was the blue light, by law you were only supposed to have a single light, usually the "teardrop" that fit on your dashboard, but some went on to challenge the Battlestar Galactica with their set ups and drove like maniacs.
