I have a few more. Commercials depend on it. Plain logic tells us that sitting for hours in front of a rapidly blinking light irons our brainwaves into an undulating jello wave. But they don't mean any harm by it. They run these tests on remote highways in the middle of the night now and then, just to reassure themselves that even if a few people actually witness astounding and outrageous things, other people probably won't believe them.
Cattle mutilations are a red herring.
I've decided they don't have anything to do with UFOs, partly because they don't make any sense, but mostly because I don't even want to think about them. They're just too yucky. There are striking similarities to be found in these missives. You can bet that whatever it turns out to be, it will likely make little sense and even less difference. I was a weird kid, but I got over it.
