I spotted this around Nørreport metro station. A sign from the City of Copenhagen. The train and metro station are the busiest in the nation. This is, apparently, a rescue zone in case of an accident.
The sign reads:
Rescue Zone
Is your bicycle gone?
Maybe it's in the bike rack on Israel's Square.
We moved it to be on the safe side. [or 'for the sake of safety']
I like the gentle, helpful tone. What a nice sign. The City moves bicycles a hundred metres away to a large bike rack on the nearby square so that the rescue zone is kept clear and they let you know where you can, perhaps, find it.
