I've been to the Purex plant. They made the plutonium for the second atomic bomb, not the first. That's why the local high school is "The Bombers." Mushroom cloud decal for your back window! The perimeter fence at the 200 East area has a great sign. It's black and yellow and at the top says "No Trespassing." Below that is the silhouette of an M16 rifle. And below that in smaller print it says "Lethal Force Authorized."
