That was a wild hail storm, Dave! I only got to see one like this in person, once. Helena, Montana, 1982. I don't know how many car's, it totaled out but, our's was one of them. I remember the street's flooding with, what looked like three foot snow bank's. Every west side window, on every house smashed. Hole's in the roove's. This hail ranged form Golf ball, to bigger than softball size. It looked like a giant white wall moving into town. We never had anything like that in the northwest. I was 16 in 1982, and this thing left a mark on my memory. Maybe, it was because I got nailed by one of the hailstone's, trying to move the family car under a tree. Didn't work, car still got trashed. Shattered grill, marker light's and glass. Not to mention, all the pock mark's throughout the body. My folk's had just bought this "Ford Fairmont", brand new. After being totaled by the insurance co., they bought it back for $400.00. We had this car for many year's, it was joyfully called,"Crater Car". Another thing that I remember well is, while checking the damage throughout, we passed a Chevrolet Dealer. There were some Corvette's on the outside lot. The bodie's of the car's looked like shredded wheat, on a frame.
Didn't mean to ramble, just thought I would share.
