Arriving in Argentina on December 28th was a major milestone in my life to begin with. Argentina being the 100 official UN country that I have visited. This was a part of the reason I wanted to do something big to mark the occasion. I felt Aconcagua was that big event, being the highest mountain in Argentina, South America, the Southern and Western Hemispheres. Basically the highest mountain in the world outside of the Himalayas and a few Central Asian mountains.
