as astounded as i am (as a canadian) by the failure of boston's city services to plow the roads, there's actually an opportunity to organize, here. if the city doesn't want to do what the city is getting paid by taxes to do, perhaps the citizens ought to organize their own councils to do so, and then refuse to pay taxes to a council that is clearly not using them properly...
parking places on roads are obviously not personal property, and can't be treated as such without violence erupting. the source of this violence is the idea, and there's no end but violence should the idea not be abandoned.
however, a council of citizens could do things like purchase a small snowblower and decide to take turns in plowing the roads.
