Katy Perry plays the pan flute atop Wayna Picchu
Yesterday at 6am I started climbing that huge mountain you see in all the Machu Picchu pictures called Wayna Picchu. Before I left for my 4 hour journey the hotel kindly gave me a pan flute to entertain my fellow adventurers along the way. When I got to the absolute highest peak of the mountain something came over me, possessed me, and woke inside of me my truest calling... #musthavebeenthecocaleaves
