So, where did the gold go?

[Adm.Lee]

Spinning off the Fort Knox issue, what happened to it? Without checking, who's garrisoning Fort Knox? If we assume that part of the pre-TDM planning involved moving the gold to a secret location, where did it go? If we believe some of the rumors about the Gold Depository (GD), is it safe from a nuclear attack, and who's guarding it? Is it still there, and no one's guarding it, because it's been buried so deep, no one's getting it out? I can't recall, did it get nuked?

I drove by the GD once two springs ago, while visiting the Patton Museum. Obviously, there are no tours for the GD.
