Today the Johnson County EM sounded all the sirens in attack mode since it was raining out here and there. Went down to Springhill to record this unknown siren. It failed, you can hear the 2001's in the background... four to be exact. The humming is the power obviously trying to feed into the siren, which appears to have a jammed motor.

Oh well, really wanted to hear this siren roar.
