My Mother kept some monster hailstones from a 1970 storm. I found them when I was cleaning out the home freezer when we sold the family home in 1996.
I think I have a small jar of hail stones from a 60 second storm that ruined our crops in 2007.
When I was a kid it snowed one year and we wrapped a snowball up with rags and buried it and it was still there a month later.
