Alfredo was really well prepared.. he gave us a lot of informations in the car… each time the driver had to stop to the gas station, he asked us if we needed something. So he likes to take care of his client. On Caral, Alfredo has a lot of things with him to explain us better the history of this site. He brought us to another site as an extra… and the lunch was so delicious. Alfredo is a really good guide !!!
