In Porto Iguazu, Argentina again

Yes, the driver was going to our destination but he had to stop at night and sleep. We decided to carry on by bus to get to the town quicker but as it was getting late, we were feeling more and more tired. The driver proposed that we sleep in his truck which was big and comfortable, so we did. When we woke up on Monday morning the rain disappeared. It was sunny and extremely hot. We felt great because we had a good rest at night.
The vegetation in the north part of Argentina is fantastic, the colour of trees and bushes is light green, so optimistic! We were very close to Brazil, about 6 km from the border. We could see very skinny and sick dogs near the road - unnourished people and animals on the road are a sign that you are in or near Brazil...
Our destination was Foz de Iguazu in Brazil but we changed our minds and we got off in Porto Iguazu, an Argentinian town. We found a hostel, had a walk in the town and wanted to take a bus to the waterfalls on the Brazilian side (they are very close to Porto Iguazu). However, we forgot that it's one hour ahead in Brazil and they let people in to the Iguazu Park until 4 pm. We were late. We got upset for this reason but only for a moment. Tomorrow we will visit the falls on the Argentinian side, the area is much bigger than the Brazilian side (in the picture). Of course, everything is expensive here as many tourists come to this part of South America to see the waterfalls.
