Turns out, anyone can have a free amusement park in their yard as long as mother nature is willing to dump plenty of snow on it.

This mystery family, currently going viral around Facebook, is now the industry leader in hommeade snow-coasters. With a deck high enough to create momentum on the first slide down, they were able to build snow banks weaving their snow luge to the other side of their yard.

By the sound from the video, it seems the snow has already become incredibly hard, but maybe if they hosed it down over night they could get a sweet layer of ice going and really up the speed/danger factor.
