Okay, to put it into perspective Camo... As your experience with roadside vigil (sp) / markers is obviously very limited.
Think of a dark, fairly commonly used piece of road, a vigil located less than half a metre from the roadside (on a bend),up to 6-8 foot high, with flowers, clothing, crosses, candles (often lit) and all sorts of other memorabilia... some times, on this dark , fairly commonly used road, up to 10-15 people standing around this vigil, often on the road and road side causing a severe traffic hazard...
As I said, it is a touchy subject as unless you have experienced it would not know the pain or heartache involved.... And as I also said, I for one would not have the nerve to tell the family to remove the vigil or any I have seen like it...
