Crowd-goers enjoyed the warmer weather and relieved some stress on Saturday at the 2013 International Pillow Fight Day. The event was hosted by Urban Playground Movement, a group who organizes free, world-wide public events. New York, LA, London and Toronto were just a few cities who got in on the fluffy fighting.
