Neither more nor less

Has anyone seen the Ghost Bikes around? They are placed at intersections where a bicyclist was killed to bring greater awareness to bike safety. There is an article about it in the current issue of Good Magazine.
 

Yeah, they're in Brooklyn too. There's one on 5th ave and I think, St. Marks, in Park Slope. It's decorated with flowers and painted white. I've seen a few of these bikes around..
