Bloomberg Philanthropies' Mayors Challenge

Can't wait to see the ideas that come of this - 305 cities submitted ideas to the first-ever Mayors Challenge, a competition to identify bold ideas that solve major challenges and improve city life. The grand prize winning city will receive a $5 million innovation prize; four runner-up cities will receive $1 million each. Twenty finalists will attend and work collaboratively at "Ideas Camp" in NY in November.
