when I was 12 my friends and I built a large ramp to jump the huge ditch that was in front of my friends' house. After a couple of tries and success I wanted to get some "Big air" so I started my run at the top of a large hill. Needless to say I had way too much speed. At the last second I chose the ramp over the ditch and flew SMACK into my friends's house. His house had that glass stucco stuff on the walls. It was messy!
