So I had the pleasure of making it down to Iguaçu Falls when I was in Brazil. It was a trip well worth making and if I ever get the chance to go back, I will. This is because of the last picture. These falls are on the border of Brazil, Argentina, and Paraguay. Unfortunately because of the last picture, we only saw it from the Brazil view. Only Victoria Falls in Africa can be considered larger but by standards of the largest sheet of falling water in the world. Otherwise Iguaçu Falls are much larger.
As you can see, similar views in all three pictures. This is because I couldn't walk. I could hop, but not fast enough or far enough. This little accident happened on the bus ride down there. We were at a stop to take a break for snacks and whatever, and I stepped down from the bus onto a curb. They took me to the podunkiest clinic you can imagine and all they did was take an x-ray and tell me what I already knew. That it was severely sprained. He said don't walk on it and I could maybe get crutches at a pharmacy. I had no luck so I just hopped until I got home and got lectured by my doctor for hop walking on it. What did he know???
So please search Iguacu falls and that will bring up some more beautiful pictures. Although pictures don't do this place justice.
