I can remember walking to school and do not remember having days off from school.
My father had chains to put on his company car, who supplied them I have no idea.
The trains ran I think because they were great heavy steam trains I believe the trams/buses ran but am not sure. I am talking about London in the late 40s early 50s, giving those dates makes me feel really old.
By the way Howard, people were not disfigured by polio they were disabled, like me.
