Ghost bikes

I saw something on one of the online newspapers the other day about some organisation which is buying up old bicycles, spraying them white and depositing them at strategic places to remind people that cyclists are vulnerable. I was idly speculating about whether they'd bother to put them in rural Lincolnshire after I'd read the article. Then this morning I saw one chained to a lamp post in the middle of the market place when I was walking to work. News come to life! I haven't a clue where I read it so I can't post the link to it.
