But why in US of A? If I hadn't misheard the treasure was of south american origin. Why would they put it up there? Convenience I guess... so they could claim it as 'national treasure'. 
Guess there's just another blunder a'la Hollywood they dictated on us..hehhe
Be reminded that there was a very big underground hall - I say again, underground - that hold all those treasures for many centuries before could be found on its prequel. Imagine how they could built such thing, not to mention the materials used: woods. Blah. But yeah, the action scenes was not to be missed. So I guess that was it supposed to be, anyway. *grin
Thanks for this honest review.
