This was, for lack of a better discription, and unusually "slippery" snowstorm.
Most snow we get around here is fairly wet and heavy. This was a light powder, which would make for a great day skiing, but not for driving.
I drive a Subaru Outback wagon which is usually pretty surefooted in the snow. For the first time in five years of ownership, I had all four wheels let go on me while I was coming around a corner (responding to the firehouse for an EMS call, no less). I was only going 20 miles an hour (maybe less), but the car did a 270 and ended up facing backwards in the middle of the road I had turned on to. No one else was on the road, and I didn't hit anything, so no harm done. I turned around and continued on my way, even slower than before!
Thankfully, most people around here stayed off the roads. We got plowed out pretty quick, leading me to believe there's some truth to the allegations that NYC suffered from a wildcat job action.
Be safe everyone!
