I was in Montréal the last few days shooting a new video project and had the opportunity to observe the snow removal strategies there. It's like a military operation, with a $120 million annual budget and 27 sites around the city where they dump mountains of dirty snow to get them off the road.
I left just in time to miss a storm expected to drop 15-20cm of snow, followed by a dose of "ice pellets" overnight. Whew.
