A couple of years ago, well four now actually, a very close friend of mine was hit by a car and died on scene. I've only driven past that spot four or five times since then, I avoid it as much as possible, but I can always see it in my mind, even though I wasn't there it's just in my head. I can't imagine having to cope with lots of these 'ghosts' across a city I work in day after day. People have already said this but this gave such a better more evocative description than any other reporting, thanks for sharing this, and thankyou so much for doing the job you do.
