Paul Ramírez Jonas' Key to the City
Something very cool a friend of ours is participating in. Sounds like tons of fun!

Paul Ramírez Jonas has created a Key to the City that is not only a symbolic award, but also a functional key—opening spaces across all five boroughs of New York City. This Key to the City is intended for everyday citizens, who will award one another the key for reasons large and small. Once in hand, the key launches a citywide exploration of back doors, front gates, community gardens, graveyards, and museums that suggests that the city is a series of spaces that are either locked or unlocked.
