A journey I took with my 3 college age daughters, and a good friend and his daughter on a 16 day vacation in Peru, 8 days of which were on a trek from Cachora to Choquequirao, then on to Pincho Unuyoc, Maisal, Yanama, Tortora, La Playa, then a train to Aguas Calientes (Machu Pichu Town) then visiting Machu Pichu and Ollantaytambo. We had 15 mules, 1 horse,5 muleteers, Guide, Assistant Guide, and Chef plus 2 oxygen bottles. The book describes the journey and the joys and tribulations. It was a great trip, surmounting passes over 15,000'. I was 61 years old when I started the journey and spent 8 months getting in shape and losing weight and getting good eating habits, and felt like I had regained 20 years of longevity, at least until i started goiing downhill, then my joints got a little sore. Funny thing though, my daughters said they had the same problem, so I don't think it was age. Am planning another trip to Peru next year. I love the country, the people, and the food!!!
