These are hail stones that fell at 9:45 PM on May 4th, 2007. This hail was from the same monster storm that flattened Greensburg Kansas with an enhanced F5 tornado (it was over 1.5 miles wide). I had went to bed early since I was going to a trap tournament in Hays Kansas the next morning. When it fell it sounded like someone pounding on my roof with a big hammer. The largest one measured 2.24" at the widest point.
