Epic Journey #2, Going out with a bang

So I was planning on working my way through Argentina, slow and relaxed, and maybe spending some time on a beach in Uruguay in December, before my family gets in, but then Jean proposed we do a 4-capital sprint, from Santiago to Asunción (Paraguay) to Iguazu Falls (intersection of Brazil, Argentina, and Paraguay), to Punta del Este (beach in Uruguay), to Montevideo, to Buenos Aires. So, it took me about 2.5 seconds to take him up on that, and we got one of our other friends interested (Angel, from Malaga in southern Spain) and bought bus tickets today.
