National Killdozer Day

It’s June 4th. It’s Killdozer day.
Info from Wikipedia about it is here.
A brief synopsis is:
Marvin John Heemeyer was born in South Dakota. He had disputes with various officials and individuals in Granby, particularly involving a zoning dispute which allowed a concrete factory to be constructed opposite his muffler shop, severely hindering him from operating his business. Heemeyer was a skilled welder and owner of an automobile muffler-shop.
On June 4, 2004, he drove his Killdozer through the wall of his former business, and tore down the concrete plant that had ruined his business. He then proceeded to destroy many other buildings, including the City Hall.
