In past decades, construction in the American Midwest tapered to next to zero in the winter. For two, three, or four months the construction workers were idle. A few carpenters worked inside jobs and electricians and plumbers continued to make repairs. (Plumbers more than usual if temperatures dropped after the electric went off.)
A different sort of construction became obvious. After each fresh snowfall the kids came out. Forts were popular to give interest to the snowball fights. Snow angels appeared in the yards. (The trick was not to disturb your fine work when you stood up and stepped away.)
And then there was the old stand-by.
My father helped in the construction of this fine specimen. I was about five years old.
