After a few milder winters, this winter has been particularly tough. A hardy few bike throughout the winter but even they have limits. As I write this the snow is thickly falling and only a few brave souls can be seen biking or walking.
The cold is actually manageable; bundle up and you'll do well. But the thick snow turning into ice on the sidewalks and roads makes it dangerous. This winter has been especially tricky with a freeze-thaw-freeze cycle that has turned much snow into hidden ice. Avoiding this ice buildup, I believe, is possible. If only the City cared enough.
