The Siren Board

I got to the Oak Park one today. and got some video.
This one is at 9 mile and Coolidge. The Compressor hum is noticeably loud.
Camera is sitting on my dash in my Crown Vic. I had my Scanner with me this time. You can hear them say "stand by Oakland County" Or something like that just before the test starts. I think the code just after is just the freq id.

T-bolt test

Nice video...reminds me of the Thunderbolt that is by my middle school. When i was little we lived a block away from it and every monday i would go running out of the house to see it in action. Also, in Middle school i heard it every monday. It sounds just like that one.
