I went over to his house after the Brea Fire Dept "Open House" event and after getting a drink and chatting; we figured we would set this off. I placed the siren in his boat facing upward and took the video while he plugged it in. The "It's a fire truck" and us giggling at the end was because after unplugged the siren, we heard the neighbor's girl yelling "Mommy, It's A Fire Truck!" during the wind down.
