It's the rainy city and this is Rainy City Stories. What they do:
This site gathers up a wide experience of living in, remembering and imagining the great city of Manchester. It uses a map of the city to organise stories linked to particular places.
And here's a press release [pdf] about the initiative:
Manchester is a city made of stories - some have long been forgotten, some have never been told and some have yet to be written. We're excited to announce the launch of the Rainy City Stories project, which invites readers to engage with their city in a new way, opening up a hidden landscape of fact and fiction.
