Air Raid Sirens at Midnight in Dallas

>If there’s a nuclear bomb about to drop over The Perot Museum, there’s no “Duck and Cover” reaction that can save you or your family from becoming flash-seared jerky.

Sorry this is somewhat off-topic, but I hate seeing this. Nuclear weapons create a very very wide donut-shaped area in which ducking on the ground is extremely helpful. Inside of that, it's roasting you, and outside of that, it's a flash, a bang, and a breeze.
