The algorithms. Maybe you'll recall that last year I wrote "Pirate Radio" which was inspired by the discovery of a body in a barrel in a lake. Here's a reminder:
"They found a body in a barrel in a reservoir
Thirty miles south of town
With a hole in the head where it shouldn't been
Somebody put the boy down
The water level's down 'cause the rain won't fall
And they're holding up the river's flow
Now the lake's telling stories like a Charismatic preacher on pirate radio..."
I never mentioned what lake it was. I clicked on a single news item that was the source of inspiration.
But the webz have dutifully kept me informed of every new development about the water level in Lake Mead, ever since. Right up to this morning.
