Waw!!! Now I am spending my vacations in Peru I remember "The Treasure on Manco". Peru have many sceneries to a plot about a episode of MacGyver, even a Movie.
Macchu Pichu is the best known. But Reciently Caral it was declared cultural heritage of humanity. At the moment, Caral is the most old civilization known in America. It is a relatively reciently discovery comparing with other places. I can imagine MacGyver there.
