I pass some of these memorials on my daily commute. Others I have passed just once, stopping only briefly to make a picture. I know none of these victims of road trauma. My interest is less in them, but in those who have erected these ad hoc shrines to their memory. Some are carefully maintained while others appear to have not had a visitor for a long time, their plastic flowers long faded and ravaged by time and neglect. These shrines are a poignant reminder of the flux of memory that continues long after the finality of those for whom the shrines were erected.
