The flight to Cusco was breathtaking, and only slightly frightening ("We don't fly through clouds here, cause there are mountains in them.") We had to depart at 5:45am cause that's the only time of day they can count on visibility being good enough.
We're doing better with the altitude than we expected. Perhaps cause of the altitude sickness meds we're taking, which make all of my fingers and Reece's toes numb. It's a worthy trade-off.
