I heard today that outside of Denver, CO was a plant that made the trigger mechanisms for virtually every nuclear weapon ever made in the US. The result of the manufacturing of these devices was that the entire area was extremely polluted. Well, after 10 years and approx. $70,000,000,000.00, the area has been reclaimed and the 4000 acres given over to the US Fish and Wildlife Service as the 'Rocky Flats National Wildlife Refuge'.
