Our trip to Cuzco + Lima, Peru. We flew from Puerto Vallerta to Lima, Peru. We left behind the heat and beachy sun above the equator. On one transcontinental flight, we effectually flew from Summer to Winter. As we exited the airport in our shorts and sandals we saw Peruvians clad in coats and scarfs. Even in the ocean, the surfers were covered head to foot in wet suits to keep out the chill.
