While traveling alone in Peru, I made friends with a Canadian and another girl and we decided to make the day hike to Laguna Churup together. We got a late start, one of the girls had trouble acclimatizing and that slowed us down. It started raining and we knew we needed to get back to catch the last ride into town or we'd be spending the night outdoors completely unprepared so we never quite made it to the lake.
But I really loved this scene along the trail back to town, after we'd asked for some directions and the person, in Spanish, pointed both ways. Not really helping at all, but we somehow made it back and drank lots of beer that night.
