The tropical to temperate shift is difficult during the winter especially. Going from green to brown, warm to cold, often wet to dry, is a difficult transition psychologically. No wonder everyone just wants to say to heck with it, I'm going tropo. TPP hadn't worn socks or shoes since the 18th so they feel pretty funny. And everything in the rainforest is so green and here the green is gone mostly until next spring. This transition has been harder, deeper into the winter. And it was easier when the participants were younger, but there you go. It would be much harder on any native of the tropics to come to this part of the world where they would wonder how people actually live here. In the dead of winter, TPP sometimes wonders this as well. Then he had a friend from Duluth, which isn't the end of the Earth, but you can see it if you stand on a car's fender. Anyone from so far south as Lincolnland shouldn't complain. So in part it is all perspective. And for us there was no jet-lag to deal with either just a shift from earlier to bed & up with the sun to see 'early birds'.
