Got to see this last weekend - was the second person through the door when it opened, actually. (Would have been first but it's rude to block your own mother out....). If you have any interest at all in South American history, the Indigenous Cultures of the Americas, the Andes, archaeology, or anything related... GO. Some of the most spectacular artistry you're ever EVER going to get to see, and probably the last time in our lifetimes it will all be in the same room. Irving is the second and last stop on the US tour.
While you're there, look at the timelines and relate them to what was going on in "Western Civilization."
