Translation of merluza

In the meantime I am listening to some Spanish CDs. They are intended for the car, but no one can tell you when to listen to it, how many times and how often. Please understand that I work a lot.
I also made a reservation for a daytrip in the nearby mountains. We went in the early morning and met again near the Huanchan road, close to the office. A ten-seater picked us up and we left.
The same evening we left Patagonia and flew to the capital of Argentina, Buenos Aires. We have waited a long time for this moment as we have not been in a city for almost two weeks and we usually love the city.
