Well, in the french town of Bugarach, those that follow the Mayan calendar winter solstice turned up in a bunch of them to deal with the possibility of the world coming to an end. They believe that a mountain in the area (the “Pic de Bugarach” in english: “Peak of Bugarag”, the highest summit at 1230 m) contained aliens living in a spacecraft, and their relatives were about to return.

If there’s one thing you’d want to take away on an alien trip who’d have thought it would be a 2CV?
