Maybe you've just seen The Bourne Legacy and have nagging feeling that you're being watched at all times. Maybe you related a little too much to Close Encounters of the Third Kind.

But the more likely explanation is that you've caught a glimpse of the federal effort to measure "naturally occurring background radiation."
Life is pretty boring if you’re a salmon growing up in the Nimbus Fish Hatchery. After being incubated in a tray, you spend six months in a plastic tub surrounded by 70,000 fish just like you. Then, it’s graduation day. You’ll be scooped into a tanker truck and dumped into the Sacramento River. But for now there’s nothing to do but eat, and the only thing you see all day are the people who feed you, like D.J. Gervin.
