sent the day with our guide and his family at a local lake which was created from the Itaipu Dam (more on the dam later). It was very interesting to see and spend time with the locals (only the guide and his kids speak English). We had a cook out with local food and listened to live music, the water from the lake was warm. All and all, a very interesting day to see how other people live their normal life. The people are very much into family.
