Took you at the event "Earth Hour 2013 - Åkersberga".
We had an event at the Earth Hour in Sweden. We met north of Stockholm in a municipality called Åkersberga. Well before the Earth hour we went up a hill used as ski hill. From there we would see the lights go out. Unfortunately I didn't see anyone putting a light out. After that we went down and those who wanted grilled hot dogs. The event organizers had made us all a lovely cake, and then they published some caches. There was quite a bit of snow in the woods, about 15 cm, but we had a fun time searching for the caches. All in all a perfect event.
