This is the last picture from the Argentinian side, but the day was not over. It was near full moon, and around full moon the park rangers arranges a walk to La Garganta del Diablo, and I took the occasion when I already was there. We got a small introductory lecture where we were asked to be silent, and not use the flash. You can guess the outcome: It wasn't quiet, and there were camera flashes all the time. (No, not mine.) After the walk, there was a dinner, and when I was back at the hotel, it was just after midnight. I crashed into bed.
