YAHOO!!
Finally! Everyone thought I was crazy when I referred to the onion snow. I live in Seattle now, but was raised in Syracuse, New York and nobody there knew what I was talking about.
So, in checking the internet, I find your site and lo! the phrase is from Pennsylvania…Mystery solved. I spent four years in Williamsport going to Lycoming College. After 50 years, I now have a real reference.
Thanks much.
