It was 22 years ago on May 10, 1990, when Eastern Wisconsin experienced its latest snowstorm on record. We're sure many residents still remember that storm which consisted of wet, heavy, snowflakes during the time that trees and other plants were in full leaf. As a result, thousands of trees and tree branches came down under the weight of the heavy snow. Many power-lines snapped as trees or tree branches came down.
