So I figured I post this here and let you all see the most chaotic looking siren I have ever seen :lol: . This Grifco 888 is located at the Narrabean Fire and Rescue in (obviously) Narrabean NSW. A while before I visited this siren I was given options for sirens to see. I noticed this 888 located at...
