One time I was riding late at night in an Industrial Park, I found a sweet corner, hit it at least ten times, at almost full speed, with a knee down, My buddy finally got there, and I showed him the corner, and "How to take it" well, I hit a tiny piece of paper, or wrapper of some type, the front end let go, and I went all Super Dave over the bars
