After the disappearance of several Los Angeles sirens lately, I went on a (COLD, COLD, COLD) motorcycle trip up to see the Cerro Negro Chrysler siren yesterday, and saw that it's still there . I fear that with the value of the Hemi V8 engines these days, somebody'll sneak up there and steal it or mutilate it to get the engine out. Just FYI; it's been sitting for xx decades with the oil cap off, so the engine is probably totally rusted inside and seized up. I didn't take any pics, as the only way to "ride by" in view is on the Glendale Freeway, so no place to stop. 3 years ago, my wife and I walked all the way up to it, and got some good pics. Since this time I was at a distance, all I can say with confidence is that it's there... It could have been damaged or or parts taken off, an I'd have been unable to tell from the Glendale Fwy.
I think this may be the only original-installation Chrysler still 100% intact in LA County, or one of two if the Wilmington Tank Farm siren is indeed still there (I couldn't find it).
