I took this yesterday when I was passing through John Day (population around 2,000). As I walked through a vacant lot that bordered what looked like an unused building, a firefighter came out and asked what I was doing. I told him that I was trying to get a recording of their noon siren, and he asked if I'd like to get the activation tones with it. Just before the first tone, there was a voice announcement: "Stand by for noon siren test." I believe that this siren is a Sterling, probably from the 1940's or 50's, and there are several of these in Oregon. I was surprised to hear the Model 2 on the north end of Canyon City activate as well. Canyon City (county seat of Grant County, population about 800) also had a Screamer, but it has disappeared from its pole. Enjoy.
