Matthew Gress: My dad went to Ollantaytambo and loved it though he was in his sixties at the time and the, ahem, tea and leaves to chew were very helpful.
On an and amusing note he got home and found a Ziploc full of said leaves in his bag.
Nam Yarasree: I have seen Ollantaytambo, Machu Picchu, Aguas Calientes, Cuzco,....etc.....Peru in 1980. I have seen las Lineas de Nazca, Arequipa, Puno, Titicaca Lake, and went back to Lima, seen Ayacucho, Trujillo, Tumbes, on my way to Ecuador. It was so great...!!! It was such a thrill. Now there are too many tourists, and el Nino....! Saludos.!
