Here’s the thing about ice: it melts. Which doesn’t make it an ideal surface for an impromptu car park. Especially on a sunny day, which will usually melt ice.
That immutable fact seems to have passed by the organisors of Winter Fest at Lake Geneva in Wisconsin, USA. When the car parks on terra firma filled up, they used the ice-covered Lake Geneva itself as overflow. But the balmy temperatures started to melt the ice while the weight of a couple of dozen cars forced what was left to start sinking below the surface of the water.
According to local reports, some people were able to drive their cars off the lake, none the worse for the ordeal, but many couldn’t be rescued and are probably now at the bottom of the lake.
