From Cordoba got 20 hour bus to Iguazu with weird Israeli guy!!! (dont ask). Went to a river i the town where we were staying where we could see the borders of Brazil and Paraguay. Met Derek who we saw in Buenos Aires - how random?!? We all went to the Argentinian side of the waterfalls - they were amazing - set in the rainforest!!! Even took a trip on a speed boat to the foot of one of the waterfalls - got drenched! lol Next day went to the Brazilian side - they were one of the most spectacular sights we have ever seen!!!!
