OK, I made it today without any problems. I took sidewalks to the main streets that were plowed, but since the sidewalks along those were buried under piles of snow pedestrians walked on roadways which force the few cars out there to drive slowly and carefully. I had to walk through piles of snow twice maybe. Some blocks had hard packed snow which wasn't bad and the Williamsburg Bridge bikeway was plowed and salted! So it was slow and harder than normal (30psi, studded tires) it was actually kind of fun. But I'm going to leave early so I can ride still during daylight.
