To begin the day we had breakfast and left for Argentina. When we arrived, the border patrol wanted our passports and stamped them. This was much different than Paraguay. It took about ½ hour in customs. We then went to Puerto Iguazu and the Argentinean side of the falls. We walked through the forest and took a few trains to see the every view of the waterfalls. We had lunch in the park. The Argentinean beef was very good. There we came in contact with people from all over the world. I even met some Americans. At the exit there were indigenous people selling different items and kids singing songs in the native language of Guarani. Then we went to where Brasil, Paraguay and Argentina meet which is called the Mark of the Three Borders. Each Country has a pointed structure with their flag painted on it. Around the Argentinean point, there were many native people selling hand-crafted items. Then we went to the center part of the city and went in to different shops to buy local items and on the streets there were many native people selling crafted items.
