Wouldn't it be interesting to know where it was planned to be exploded. We'll never be told. I believe if more details were made public, more people would take the terrorism threat seriously (especially in the tentative targeted area).
I don't remember who but someone on Coast to Coast a while ago said that they had found a nuke in Boston.
He was there and saw the whole thing but it is not being released to the American people. I think it was the same one who said we had OBL bagged and tagged. For what thats worth.
