Walking in the city after a snow storm is difficult for anyone. City governments seldom clear crosswalks so that pedestrians can cross streets. But for persons with physical disabilities crossing a street is not difficult, it is impossible. How many people must remain inside after a snow storm? Many who have power wheelchairs can travel in the streets. But access to sidewalks remain a barrier for many who use wheelchairs, persons with guide dogs and persons who use canes. That is not to exclude women who push a stroller with their baby. They cannot use the sidewalks either.
