Chicago can be heard testing their sirens for their monthly blast during a couple of the voice messages. The echoes on this thing were absolutely insane, especially when it faced the golf course and down a residential street with tons of houses. Despite what some of ya have to say I am very impressed with Whelen sirens! Location: Union Ridge School District, Harwood Heights, IL Testing Schedule: First Tuesday at 10 Testing Today: 10:01
