"It feels like breathing through a t-shirt" - SA mountaineer, Leander Opperman
Leander Opperman might seem like your average South African but there aren't a lot of South Africans who can say that they have climbed one of the highest mountains in the world! Just last year Leander was scaling the peaks of Aconcagua in Argentina along with 14 other people. Aconcagua is the highest peak in the Western Hemisphere. It is more than 6,706 meters high, though the exact height of its highest peak has been the subject of some debate.
