Here is my story:
It was the end of the ice age but there was still lots of ice and it had melted into some new shapes, some cave men had began carving ice water slides, but only the brave took it, since it was so cold and the tube had cave in's often.
The water tube was used more often for transferring food and other stuff to the near by tribe's, there was soon a ice system transferring food and some hard headed people to far away villages down hill. It was such a ride that some far away chieftains came just to have a few rides. And the small village gained popularity and prospered greatly. However a nearby village which had been jealous of their wealth began construction of a better tube system. Soon there was what is today known as the battle of entertainment!
