I don't care how dangerous it is, this looks like it was a lot of fun. Owen says they spent over ĆĀ£100 on roman candles alone. You can see Owen in this clip. He's the one shooting his friend with a roman candle at point blank range over some bushes.
One of the riders in a bike race looks at the camera and loses control. Once he falls down other bikes start to hit him and pile up. I bet there were a lot of angry bikers that day.
