Nice find! I'm only a few miles from Leadville this week in Vail, and I'm always looking around for sirens. None found here, or in Avon, and I would have thought they'd have some sort of warning for avalanches. Been too busy to really look into it, but I'm here a couple more days, so maybe I'll hav...

No effects, just a cheap camera which I put it on the highest resolution setting and that reduces the image quality further.

You say these are crap photos, but in all reality, they're quite excellent. Those DSAs look to be relatively new as well. Don't see them around too often outside of Hawaii. Nice job! I was talking more about image quality, but thanks. I'm guessing these were installed in the past year or so; I'd ne...

Come to think of it, it would be cool in a dark grey-blue or something.

Almost every siren is yellow or grey. It would be cool to see a change.

So, for the test today I went to Bradley Elementary, where there is a '50s Model 3 on the roof and a less old 2001DC. I was really hoping both would sound, but sadly only the 2001 went off so I focused the camera on it until the test ended. http://www.youtube.com/watch?v=399Y8KxUDBM Because of this,...
