Milk float - you were lucky! I lived in a village in Northamptonshire at the time - whole village street had a carapace of 1/2" ice from gutter to gutter. Canals well frozen (it was Braunston on Oxford and GU Canal junction) - just as well as sledge hill led down to canal. Proper winter that was, as you say. Kids today, don't know they're born.
