Reminds me of the documentary on PBS the other night about nuclear waste. The government and the brainiacs began churning out nuclear weapons without much, if any, forethought as to what to do with the waste of it all. They showed old video of workers tossing containers in cardboard boxes into a not very big hole and then covering it up with an earthmover. Scary.
