Iguazu Falls and 3 countries in one day

So its almost midnight and I should be sleeping but Im not. Its been a hectic 3 days! On Saturday Alex and I arrived in Foz De Iguazu, after our looooong bus ride from Rio. We got there around mid day, found a hostel, and went straight to the Brazilian side of the falls. Wow! They were spectacular!!!! Then yesterday, Alex and I left Foz de Iguazu for Puerto Iguazu, Argentina. We crossed the border and found a hostel, and then went to the Argentinian side of the falls. We spent about 6 hours there. There is a lot more to do on the Argentina side. We walked along the trails and also went on a boat ride that takes you under the falls so that you get soaking wet. It was great! However, it was also really really hot and humid. I dont think I have ever been as hot as I was yesterday. It was a horrible feeling, trying to enjoy something so beautiful while trying to also tolerate the heat and not get dehydrated. It felt wonderful when we were finally able to get back to our hostel and take a cold shower! Then last night we went for some drinks with some people from our hostel-a British guy, an American from Vegas, and 2 Koreans. We had a great time! It was actually pretty hilarious trying to have a conversation with everyone because the guys from Korea speak some English, but I think many things were lost in translation, and everyone would just end up laughing. We stayed out kinda late and this morning I didnt feel all that well. The British guy, David, convinced Alex and I to go into Paraguay for the morning so that we could help him return a camera that he had bought there a couple of days ago. So we hopped on a bus that takes you across the border to Brazil, and then across the border again into Paraguay. 3 countries in one day, not bad! However, we didnt even get a stamp to enter into Paraguay. So technically, we were there illegally. Anyway it was quite an experience in itself because there are soooo many people in the streets and shops. Everyone wants to sell you something-even when you say several times no thank you! In the hour that we were there, I think at least 10 different people stuck fake puma socks in my face telling me that i could get 6 of them for some amount of guarani-the currency there. Then we had to wait in the street for a bus to come for about 45 minutes and then you have to hop on, there is no bus stop. We had to catch a bus into Brazil, get off, and get another one to Argentina. It was ridiculous, and I was glad when we finally left. After this whole shindig that took around 4 hours, Alex and I again headed off to the falls, to see the garganta del diablo-Devil´s throat, the best part. It was the highlight of the park. The amount of water was intense! See for yourself in the picture! Tomorrow we head to Buenos Aires. Alex and I got the most luxurious bus they have-seats that turn into full beds and food service on the bus. Its also a double decker. Alex is pretty psyched about that!
