Iguazu
After saying goodbye to Buenos Aires (and Milhouse), Arsalan and I took the 18-hour bus to Iguazu in the north of Argentina. If you haven't heard of it, Iguazu is one of the most beautiful places in the world situated on the border of Argentina and Brazil, with an incredible series of waterfalls numbering over 150. There's not a whole lot to say other than that if you can, go check it out at some point in your lifetime. It's well worth the trip.
