For this very warm first Wednesday of October, I ventured up to Crystal to record their 3T22, located by their city hall/police department and library. I first recorded this siren with my old camera back in 2018, and finally got around to getting an updated video of it. Unfortunately the wind decided to wake up and choose violence, which wasn't exactly ideal, but this was still a good test overall. It did the usual Hennepin cycle of a minute of alert and attack, and was just as punchy as I remember it being.

Sirens in Hennepin County, like most of Minnesota, are tested on the first Wednesday of each month at 1PM.
