I haven't been ice blocking since...

There was one time I went ice blocking with some friends, and it was the last time I ever went ice blocking. For those unaware, you can take ice blocks and put towels on them, you sit on them and you can slide down a hill. It's like sledding in the summer with wetter results. Well this hill had been ice blocked pretty heavily so the whole hill was wet and slick. I was up and I started going down, it became too fast and my ice block came out from under me, but I kept going on the wet grass. That is until my rear end collided with a sprinkler head tearing it clean off and creating a water fountain. I had a large gash on my bum after that. That is why I will never ice block again.
