Dogbert, I know this is cheating, but it isn't legal to take pictures of the Electric boat facility in Groton, CT. And they're REALLY strict about it. But there's big signs up all around the facility to let you know. Not like you can't get up on a local hill with a telephoto lens or anything like that....
(Hey - small hint to General Dynamics - painting your name on the side of the building in huge letters makes it REALLY stand out from a distance)
