I was about 7. Our house was right on the corner and the street made a very sharp turn around our yard. I'd come down the hill and turn that corner as fast as I could (wonder why I love streetbikes so much now!), even though my parent's would always tell me not to, I'd still do it. They kept telling me I'd either crash or get hit by a car. Well, I crashed, hard! Still have the scar on my knee to this day! Worst part of it, my girlfriend brought my bike home for me
