It was five in the morning, dark and cold. We were waiting in a long queue of other impatient people who wanted to walk up to the Machu Picchu. We'll get there before first buses and maybe have a chance to see sunrise at the Sun Gate. Our plan was perfect, we only needed to show our ticket to some guys who looked like something between army and police officers.
Suddenly, out of nowhere, we heard buzzing sound. Insect was obvious suspect. At first we ignored it but when it lasted more than fifteen minutes we started to look around.
There were not many shelters to hide. But we found one. There was a place under one huge rock. Not much space, roughly one meter between ground and a "ceiling". So we crawled under it and realized that it was used as a toilet by many hikers before.
