You know the drill. People get out their snow shovels and clear just enough snow to make room for two wheel tracks. Then, after pulling the car out into the street, they put their chairs down in the parking space, to protect the results of "hours" of backbreaking labor, and incidentally making it impossible for snowplows to get through. Then we have a thaw and a freeze, and everything turns into solid ice, with only half as many parking spaces there would be if people had concentrated on getting the snow out of the way instead of guarding "their" parking spaces.
