Chrysler Hemi-powered air raid siren

I remember them as well. I heard them at the Ravenna Arsenal. Grew up about 25 miles from there in the late 60's and you knew when they were doing some kind of test for sure. They used to park one out by the Route 5 bypass entrance years ago. Went by there last summer and that entrance wasn't even there anymore. Place has changed so much. Looks like it was never even there.
