After three months spent travelling South America, Matej Košir's favourite memories include swimming in the geysers at 4300 m, driving on the roof of an old jeep over the biggest salty lake in the world, climbing the active volcano Villarica, walking along 20 km long sand beach, seeing more than 400 years old trees, visiting a town called Ushuaia, attending a football game in Buenos Aires and many more.
