We visited the famous lost city of the Incas. It's no wonder why so many people - up to 2500 a day - make the relatively complicated multi day journey to the site: it is an impressive structure in a stunning setting. And there are so few others mountain top settlements with equal grandeur: few if any other civilizations possessed the cheap manpower, discipline, ambition and impractical preferences to build so far away from typical means of transport, easy agricultural lands and a predictably flowing water source.
We explored the site (Peter found an Incan mummy down in the crypt!), took a nap at a resting place and made up all nature of challenges the Inca likely faced, particularly battles with their fiercest enemy, the Maya. Nathan largely failed to see the site since his nose was buried in the guidebook; I'm sure Peter will post the photo series at some point.
