I haven't seen a radio with a "CD" mark since... I can't even remember. The library and county court house used to have shelters underneath, with 55-gallon drums of water and boxes of cots, bandages, and supplies. When they built a new library a few years ago, they hauled everything off to the dump. Helloo, people, there are still tornadoes and floods and earthquakes... but their focus was so narrowly on atomic armageddon the idea of having a chunk of town wiped clean by tornadoes (it's happened before) doesn't register.
Maybe they don't expect to deal with anything at a local level any more, and planning has turned into some sort of cargo cult where giant FEMA helicopters come swooping down loaded with goodies. Years ago when I was concerned about the disappearance of the shelters, the only answer I got was "we don't need those any more" and a selection of pitying looks.
There used to be Emergency Broadcast Signal ("this is only a test") tests on the radio. Those went away years ago; advertisers began using the EBS alert signal in ads, along with the usual crying babies, ringing telephones, beeping pagers, etc.
The only piece of the old Civil Defense system I know of that's still in operation (locally, anyway) are the air-raid sirens. They were going to take those down before they got reminded they're used to warn for tornadoes, too.
