We weren’t all that poor but I remember plastic bread bags on real snowy days. It was pretty embarrassing because I was the only one.
That is why I had never heard of them. I can count on one hand the number of big snows we had from 1950-62. Now ice was another story. We had a picture of my oldest niece being held by someone in front of a tree covered in ice. Think that was winter of 50/51. The biggest snow we had was about 58/59.
