She had 24 hours to track down an unknown number of Americans trekking the Incan ruins of Machu Piccu, a five-hour train ride away, so they could escape before its airports shut. Then she had to figure out how to get anyone else left home.

Eventually, she helped some 1,300 Americans return on 10 chartered flights. She and her husband are staying put, as are the 30 or so Americans she keeps in touch with still in Cusco.
