Plus there is a story floating around about some "salted" tungsten bars plated with gold.  It would be a major undertaking to remelt and reassay all the gold bars in certified storage around the world.

I'd personally like to see the fed audited as well as a full independent, and complete inventory/assay of Fort Knox to make sure it has not been compromised along the way.

I think the last viewing at Fort Knox was a limited congressional viewing of some of it in 1974 after there were rumors circulating then that something was amiss.

I guess it goes back to Reagans TBV "trust but verify"
