The pictures here do not show the reality of streets crowded with vehicles, drifts, salt & dirt and no place to park. They show how beautiful and deadly conditions can be when snow is driven over, not plowed or salted and then frozen. Oh and the potholes!
Even a minor snowfall can turn into a sheet of ice overnight. Conditions seen to the left and below were difficult to even walk on.
The key is getting snow off quickly so it is not driven over and the sun can warm the street.
