You know you've been street racing excessively when the city has to dispatch an asphalt grinder to remove the thick layer of the racing slick rubber that you and your hooligan buddies have laid down with thier street machines over the years.   

We actaully came across this photo in a thread titled something like, "Washington Blvd. Dragway closes." Street racing is dangerous folks, don't do it, even when you think your secret spot is safe, it looks like someone will eventually take notice.
