That inch of snow caught everyone by surprise and they didn't treat the roads at all.
I had a 7:30pm meeting that was fortunately cancelled, and I just sat at home on my couch watching all the stories coming in on social media and watching the cars failing to make the corner on my street and then once they got straightened out again struggling to make it up the gentle slope (not even a hill) in front of my house.
Check out the time stamps on these two screen shots I took last night. This is way past rush hour.
Look at all the accidents at around 8PM!
And the traffic jams still going on long after the snow had stopped.
This was 10:13PM!
