Events: Snow Day in Toronto, Canada

Last time, I reported about Newmindspace, an interactive public art movement, founded by 2 students in Toronto.
After parties in the subway and street cars, capture flag games, picnics and massive bubble battle, they propose a Snow Day:
Snow Day will be a fun winter afternoon with snowpeople, sledding and epic snowball fight!
Notice for this event will come very shortly before the event based on weather reports. The first major snow Toronto has, either on a week-end or school cancellation day, will trigger this event/
Snowball fight!
Pics coming soon.
