We did 1200 km in 2 days. Trucks in Argentina go long distances because drivers drive for 12 hours per day thanks to mate I guess :) The story from hitchhiking is already written
On our way back we thought we were on lost position because we were set up with truck driver at 12 but he forgot about us so we started too late. We were waiting for two hours when a young man stopped and took us with his pick-up. He drove very fast so we made up that lost time. We got out before Posadas and waited for another transport on intersection. Paul went to the supermarket for some cookies and suddenly another driver stopped.
Another day was more lucky and we stopped the truck that took us to Buenos and we had great lunch and snacks on the way with positive driver.
I was going to buy a proper cup for mate because I drink from my metal mug which is a shame but when I saw this I thought I prefer my metal mug to hooves :)
