at JFK waiting to be able to check infor the flight to Lima than Cusco.  Packing was challenging I will be going from  winter in south america and a high elevation where the low last night was 34degrees to the jungle at the equator. That and my desire to travel as lightly as possible but needing to carry a tent and sleeping bag and camping gear Made packing very challenging. I'm not going to be warn enough given what  I have to wear but I plan to buy clothes in Cusco or at least some sort of wollen blanket or coat.
