From Good Magazine:
"A hundred designers, 10 urban challenges, very little money, and no sleep. That's the recipe for 72 Hour Urban Action, a three-day marathon for designers to improve their city."
The first 72 Hour Urban Action debuted in Israel in September 2010.
"With such a successful model to build upon, it's time to bring the experience to other cities. So Los Angeles designers, hold onto your hardhats: Halbrecht will be coming to Los Angeles on Wednesday, April 20, at 8:00 p.m. as part of a 72 Hour Urban Action road show."
