I constructed a rail system out of unused fence posts on the side of a 35-foot mountain of dirt. I then removed the wheels from a Radio Flyer(little red wagon), positioned myself at the top of the rails, and flew down the side of the hill. I had not considered the way I would be braking/decelerating until the moment before my wagon collided with the ground and sent me flying/rolling about 7 feet into a patch of thorns.

That was a fun day.

Later in the day a buddy of mine went down the rails and somehow snagged his hand on one of the fence posts and cut a large gash between his thumb and index finger. He managed to pull the rail up out of the ground and it came with him. The crash at the bottom of the hill didn't help matters, and I had to drive him to the emrgency room.

The best part was telling the true story to the doctor and him not being surprised.
