June 28 – On this date in Montana history in 1982 a terrible hail storm with grapefruit-sized hail stones ripped apart the Capitol City of Helena. Insurance adjusters were called in from across the nation to deal with the thousands of insurance claims. Millions of dollars in damages resulted in the region -- from dented and windowless autos, to 35 heavily damaged National Guard helicopters, to crop damage. Roofer’s nails were still causing flat tires months later as nearly all roofs had to be repaired.  Montana Historical Society personnel spent the night in the building protecting priceless artwork and collections when 47 windows were knocked out in the building.
