During the winter, I used to volunteer a NPS visitor’s center.  We would get a lot of international visitors who thought the descendants of the Ancestral Puebloans still lived at the ruins (to be fair, they didn’t know the history of the southwest).  They were genuinely perplexed why no one was there, which took a great deal of explaining how the site had been abandoned 500-600 years earlier (and I am TERRIBLE at speaking French and German).  It was all well-intentioned, but I think I left both the visitors and myself confused.
