hailstones

There was hail last night. Some in Rochester, and even more in Byron and Dodge Center. But how large were the hailstones? They were described as "pea" or "marble" sized. "One inch", but that doesn't paint a picture. I think we still get the "pea" description, but how about the "marble"...
