I would say you have never fought on a street in your life you big Dutch gay.
I attended my first NLD in 1987 at their place and in the intervening period have never been involved in violence of any sort a the event, or on the day of the event. That is not to say it does not happen of course.
I love it for the atmosphere, the edge if you will, the mere fact that the crowd is up for it compared to 36 other games a season.
