I dislike the flowers in plastic wrapping, tied to trees, lamp posts & flyovers (have seen all of those). I cannot understand what comfort there can be in reminding yourself, family or friends of the exact spot where a perhaps violent, tragic death took place, surely a reminder in a more suitable place is far more appropriate. There is a beautiful viewing spot near me that we used visit regularly, wonderful views down the valley and when we last went about 18 months ago so much of the area was given over to markers, flowers etc., some for pets (dogs presumably) and some I think were ashes of loved ones, very recent scattered about. I would have thought this was illegal but we have not been back since. Old stone markers, the crocus idea I think are more acceptable. The sea of plastic wrapped flowers, teddy bears, toys and other sundry items left out in streets are not.
