The sun is shining, and air feels surprisingly warm when we walk on a 35cm ice that covers a frozen lake in central Finland. The heavy sledges move nicely, because there is not much snow on the ice today. The journey isn’t far either, as we’re by the city of Kuopio, which is surrounded by Finland’s 10th largest lake. Despite the temperature of -10˚, I need to take off my hat—the sun in early March is already warm, or it could be the fact that the heavy sledge is following me obediently.
