On September 21, 2014, a day of climate action demonstrations around the world, a regiment of stalwart volunteers fanned out to display banners at highway overpasses, heavily-trafficked avenues and shopping malls.
Thanks for the success of this action must go to many people—too many to mention here. But special recognition must be given to a few who dedicated many hours to the project: Katy Polony, Martin Mackerel, Anne Donjacour, Sara Greenwald, and David Solnit. They hatched the idea, worried through the details, dipped their brushes, and wrangled the troops. Thanks to all!
